me watching Rob make a wiring harness knowing I’ll literally never have to do it in my life
You may get to that point. I used to hate wiring until I worked at a shop for a while and realized that given proper tools, time, and some planning you can stop soooo many issues from arising with a solid harness.
Very niceeee
Ikr 🤣. Given that tho I still love watching the content
Life is funny. Never say never.
Damn glad I don’t have too
one of the very few automotive youtubers left where your still learning as you enjoy
Check out Jimmy Oakes too, jimmy and rob are the only two I watch religiously
Can't wait to see HP Academy come chime in on your harness building. I'm sure they're loving your thorough and no expenses spared harness now!
Currently doing my HP academy wiring course and it’s brilliant
Always awesome to see what Rob is up to! - Taz.
I do this professionally with fancy tools and machines so it's really interesting to see the diy perspective.
How long would something like this take you with all the proper machines and tools?
Just remember that when sizing wire, that the length matters along with current. So a 20 foot wire that needs 25 amps needs to be larger than a 2 foot wire. I'm sure you've thought of that, but I thought it needed to be said, rather than just using current to decide on wire size.
Very true and accurate
You need to look at the acceptable voltage drop over the wire. A longer wire given the same current as a shorter wire of the same gauge will get hotter assuming there is no cooling. But there is always cooling, so the limiting factor wire length value is usually determined by the acceptable voltage drop. The acceptable voltage drop depends on the load's requirements.
I love it when the comment section has actual good advice and isn't full of idiots
@@47EZ_DRIVER well yes normally there is adequate cooling but in such a tight wire harness the inner lines certainly are not cooled
@@Spinner1987CH insulation rating also is important.
1:12:20 The loops are called service loops for a reason. It should never be the last line of defense. All the strain relief should be achieved by the potting compound and boot adhering to the connector and to the DR-25. The service loops are solely for servicing e.g. replacing damaged pins and should never be subject to any form of strain.
Also when using those mixer-tips remember to discard at least the 1 or 2 cm that comes out first.
It is amazing to see Rob, a DIY that started with the crappy rat net harness in the OG 3 rotor, and mature into a professional level race spec harness builder. It shows his dedication to being a DIYer and commitment to his fans as read all the comments and invested time, money and energy to get into this level so people can learn how top make a top notch harness.
This makes me want to go over all the wiring with my dad that he did on our fc. It was small block Chevy powered but he managed to make everything factory work. Tach, speedo, water temp, power locks, windows, rear window wiper and even the sun roof. Younger me was much like Rob in the beginning and wiring was not my Forte to say the least lol. My dad on the other hand can look at a wiring harness sitting on a bench and start picking it apart. "these are injectors, this is oil pressure, this is temp this is this and that and the other thing too!". Old man blows my mind quite often 👍
i added a spade connector to a speaker wire today and now i act like i can understand what hes doing
Rob I just want to say thanks for the content on all the wiring because it’s made me confident enough to build a custom harness for my 2jz using the ecu master emu black
I'm excited to see this front bumper tho I can't imagine what ahura will look like
Same man, it's all starting to come together and look like an actual car
@@Matty.Hill_87 I also want to see a 3 rotor turbo in the rx8
You can remake most custom fenders hoods latches and parts but a custom wiring harness like that will be hard to match!!! Great job Sir!! Most people don't have the want to create like you do....
Hey awesome vid!
For the shield of the twisted pair, make sure you land it on one side and not both. Landing on both side can create circulating current and fuck your signal up.
Land the source and float the field
Hi Rob, nice to watch the progress of a wiring harness. I’m wiring an homebuilt aircraft at moment and robbed out a heap of MS connectors from a warship HMAS Perth before she was sunk. The connectors are all referenced as Backshell connectors and are all built to Military specification (Mil Spec) MS.
Rob you are by far one of the most real automotive CZcamsr’s out there, thank you for sharing all of your crazy adventures and your crazy cars with us. You deserve way more than 960k subs.
You need a fold out wood table for harness making. You can run screws at different junction points and it really helps keep things organized and holds the wire from twisting back up as well
why go tried in true when you can go mad scientist hahah
thank you, Rob. I was shocked that this ended so quickly. Felt like 20 minutes. Definitely want to see the next one ASAP!!!
This was only a portion of full thing, he didn't show installing any connectors on the end, then he still has a good bit chassis wiring to do still as well. I doubt this is the last we see.
Spent a large portion of my life in structured wiring. Beautiful and therapeutic
Rob the only thing I would reccomend different is a p touch that does shrink wrap. something like an E500 or rhino labeler. oh and some klein electricians shears. homeless despot has them.
Loving the content, id be so overwhelmed on where to even start. Rad stuff
Power and ground
The only thing that catches me off guard in your videos more than the sudden endings is the flawless transitions for Keeps advertisements 😂
This is probably the most detailed video about the wiring of the car from all that I have seen.
I worked in an Harness factory. I worked on 45° panel with all kind of forks and connector holders. The wires are all pre-cutted, crimped and attached one end to one connector. Then we just guide the wires inside the forks. The forks where perpendicular to the diagram that was on the panel. Then the wires were isolated, with all kind of tapes, then tested on a computer.
I think I would have liked to see some heatshrink on the pins. Although they are in as aluminium socket, they’re awfully close to each other in there, but I’m no expert.
Hey Rob, love the videos.
Do you think you would ever release some sort of notebook or poster/blueprint for the 4 Rotor? Like a book with all the hand drawn notes you took or maybe even a shirt with the art work on it being some of your notes?
this is a pretty cool idea, maybe a blueprint poster with the car dimensions and rough sketches of the final body work with also a 4 rotor engine diagram
I think that is a brilliant idea. 10/10 would buy
Larry Chen poster print please
Oohh imagine like a coffee table book filled with pics of pictures from all the steps, from the previous build, to the harness, to the costume body work, plans and blueprinty stuff like you said and of course a whole bunch of photos of the finished lady in all her glory. Also maybe like a "class photo" with Rob, Isiah and all the crew that have contributed to bringing Robs masterpiece to life. Would be an awesome way for fans to throw some support towards this and future projects.
@@JustATypicalGinger i’d pay $$$
53:25 The lacing works much better when using either marline-stitching or figure-8 stitching. This is how I was taught for making/repairing electronics harnesses on shipboard equipment.
Watching this makes me realize that you don't have to be scared of making your own wiring harness. You just need to take your time and plan things out. Thank you, Rob, for always diving deep into your projects and bringing us along for the ride!
For some reason that only felt like a 40 minute video.
Personally I've not done much wiring in cars outside amp/speaker installs, but I'm glad to see I did at least a few things right even if there's clearly a lot left to learn!
Love the methodical approach to the planning. Take notes, draw schematics, label everything. It's not insurmountable, just do whatever you can to visualise what you're doing and it becomes "easy"! :)
I think the most impressive part of all of these projects is your capacity to not just learn a new skill, but dive down the rabbit hole of each skill you learn.
CNC machining
Harness building
Tuning
Chassis fab
All skills you’ve developed far beyond the typical “home gamer” efforts we see throughout the broader content creator community.
Your capacity to learn is quite impressive
Thank you daddy Dahm for blessing this friday with one of your videos
When wiring turns into an art form. So freaking clean.
Keep up the good work, two things - stick a tape scale to your wire rack, makes it easy to make repeat cuts. Also use a dressmakers tape to measure wire runs, it follows the cars contours better.
Yooo another harness video! I love them. Another cables lesson with doc Rob!
That UPS story alone is gold
i see 1.5 hour long rob dahm video, i clear my schedule. its gamer time

I use RapidHarness to diagram and dimension all of my wiring stuff, makes it really easy to organize where wires go and figure out what you need. I'm sure the Haltech software can be a great help too, but I'm always scared to have stuff only on paper because then a computer can't check it. We love us some wiring baybee!!!
Worked on engineering documents all day prior to watching the video. Laughed to tears seeing that diagram Rob 🤣
You're awesome, keep it going!
I don't even drive but love every minute of these vids
Rob it's outstanding, amazing, and so many more things to see you go from having your car in other shops to diving in and doing it all yourself. And not only doing it yourself doing it better and better and making changes to improve the build and your craftsmanship. It's fun to watch.
You have no idea how much I want to be at your shop right now making wiring harnesses and running them through your car. I have a degree in avionics so this is literally right up my alley. All of this stuff comes right from aviation.
one thing you should mention if you compare your wires to high end motorsports like f1 they dont run on 12V they all run on 16V to get the amps down

I cannot wait to see this project get finished. It is going to be absolutely amazing!
Rob, seriously, your content is wonderful.. even the longer videos, I cannot skip a second
Now you can have a drawer with various lengths of wire!
Perfect timing lol I was just listening to you and Matt Smoking Tire Podcast at the Valvoline Booth @ SEMA. You’re the man! 🍺
Rob is so smart to be able to do all these things on his own. He's a very humble guy he loves to say who is smarter and more experienced when he's really smart and has tons of experience too
Rob! Try using bread twist ties instead of zip ties when making harnesses! The plastic coated ones work much better than the paper covered ones.
Oooooh yes. 10 second old video 😍
Little trick. Use a Q-tip with alcohol on it to wipe the seams of glue at the edges of the boots after they are fully recovered. Will get the excess off and evaporate immediately not affecting the glue that stays behind
This is becoming one of my favorite channels to watch.
no other channel on youtube actually teaches you like rob does.harnesses are intimidating to me but ro does an excellent and thorough job of teaching what he knows
I've personally seen a leaky oil pressure sensor push oil all the way through the wire harness and fill the connector at the ECU on a Mini Cooper.
Dude you are killing the game with your build quality bro...every year you just level up even higher..glad your getting the recognition from companies like Home depot with tool mansion lol...
Your game has stepped up incredibly since you were doing the suppressor test(when i subscribed) it’s so cool watching this car and your skills develop over time. It makes me want to level up my game as a mechanic.
Seeing Rob do that Engine harness and all the options a Street car can have is amazing. Great work looking forward for what is Next...
Seeing how much time elapsed through this video and only really getting the engine portion of the harness worked on really shows just how much effort goes into these projects being on a different level in comparison to when the 4rotor was just a dream

Me watching rob make a wiring harness knowing I’ll literally never be able to afford the same connectors and instead use cheaper ones
Thank you for showing a nice clean well wrapped waterproof sealed harness your way looks reasonably right and clean.
I used to have a Jedi braid in elementary school... Basically a rat tail on one side of your head. This makes me feel more connected with Rob lmao

I love these long videos very much, I always watch every second of them
Love the simpli safe commercials and how you “use” them and there’s the real full blown new adt alarm box on the wall to be the real protection.
I can’t put the finger on it but this kind of content is amazing to watch to me.
It’s a bit slow and with an information overload but in the end very informative and entertaining.
I’ve seen that tape used. High end stuff.
Nice to see.
As a former ah64 helicopter mechanic the plastic pinners ive never had luck with, luckily i have some red white metal ones and yellow orange. Beautiful harness by the way.
"My Man!" I've been watching you for years and I really appreciate that you not only build killer cars...but you teach and share knowledge. Keep it up...we'll all keep watching. Can't wait to see it all done.
26:09. I Love the Head of hair! You need to do a Keeps segment where your hair is slowly blowing in the wind and then it just says "Keeps" at the end. No talking, nothing. Just wind noise.
Really been enjoying all the back to back content recently. I’m enjoying this specifically because im hoping to build cars to almost this level in the future
Wow, a simply astounding amount of work and attention to detail on this harness build, especially for your first time.
It looks amazing.
Its not his first
This is gonna look so clean and worth the effort and time to make it this way. I can't wait to see more of the 4 rotor content! Keep up the good work Rob! We love the videos.
I like that you let us in your thought process for the build. It's relatable sometimes. (Othertimes I'm speechless, just in awe of the result)
RaceSpec has an ECU header plug kit for the R5. They are special because they take a gold plated, solid body contacts instead of the fold over contacts. You would also need the DMC MH860 crimp tool and RaceSpec 1.0 positioner.
Am I the only one who finds wiring videos satisfying
Thank you Rob
Huge props to wiring your own car. I feel like this is one area most of the guys in your field don't touch
Mr rob, you started putting up videos right when I got super busy and don’t have time to watch them, I can’t wait for the weekend
This video is inspiring. I have been planning to build my own harness for my project, this has shown me a much cleaner way of doing it. Lucky for me it's just an MG Midget so as long as it comes out better than 72 British wiring I will be happy.
Only Rob can make an hour and 23 minute video on doing a wire loom from scratch feel like a 15 minute video.
that's epic. i know these videos are long, but i love it. excellent craftsmanship, thanks for sharing.
I work in the Aviation Industry, and those “Mil-Spec” connectors are called Cannon Plugs or Cannon Connectors in our realm. Rob’s very right, they’re super nice and definitely military/race team grade. They’re quick to disconnect which makes it very easy and convenient for removing panels/components. I’m amazed every video at the amount of thought and dedication that Rob puts into this build.
22:43 "I'm like a bird, I wanna fly away" lol. 🤣🤣
1,5 hours of my life totally not wasted watching a harness being built by a person that goes in 200% to learning new shit, because reasons! I love you Rob. Keep it up, this is so cool to watch.
To anyone wondering those MILSPEC connectors are no joke I literally used those barrel connectors to hook up maritime electronics like radar and radios on masts that are exposed to salty air and sea spray all day every day for years. They held up.
I'm so happy to see that you've switched to Haltech, awesome company, great support and a great ECU. Nice work Rob!
I was so looking forward to this harness video. I was mesmerized by the last wiring harness video.
Can't wait to see the before and after shots of the harnesses. Awesome work!
As someone who is embarking down this path currently with my own project car I cannot tell you how much i have enjoyed watching these wiring videos Rob. Please keep them coming, I love love love watching them! Would you be willing to share your spreadsheet layouts for your harnesses? I am still trying to find a good way to organize all my wires without buying something like rapidharness
I do this for a living but for aircraft and nothing is more satisfying than once it is installed and everything works.
You've inspired me to do this on my next car build. Well done and thank you, Rob. I am so happy with how much you have grown.
I love when he uses software-development terms in car building. This guy is a genius
Word of advice, start by wiring from the end point and route everything up to the dash. So instead of starting from the Nexus and wiring a connector there, and then trying to fan it out to devices, start from the engine compartment, wire all your injectors and sensors, route appropriately to firewall grummit or connector, and THEN put the connector on for the nexus. Way easier than the other way around, since you only ever need to worry about what you're wiring at that moment, the harness just takes shape as you progress, and you always end up with proper length wires. You also don't need to measure anything beforehand, just wire things, route, and cut when you're at the connector.
Great advice, I hope he takes it, although it doesn’t sound like it. I work for a place building electronics and wire harnesses for military planes, rockets and satellites and we always start from the end.
We are proud of you Rob

Probably your most satisfying content to date. Great work buddy! 😎
was so happy to see my boy bought a pan-a-vice. they are fantastic for electronics work.
I love watching this stuff, so many good ideas that I can apply to my work. Currently building an audio snake for rewiring my stage.
I do this at work every day and I love it. Not building engine harness but we use the same
Connectors on our electric torque wrenches for
Building wind turbines a lot simpler than this as it’s just one end to the other end on a 20ft span. But still love doing it so much. And rob I will say as a semi professional who has been doing this line of work for 7 years, u did a pretty damn good job for your first time going this extreme. And if your curious on the tools I repair, build and calibrate u can google “E-RAD BLU 3000”
That is the best looking harness i have seen on that car to date. Keep up the good work. I am definitely looking forward to seeing this car complete.
Wire color depends on the industry. In industrial equipment we use the NFPA color code. AC power is solid black. 24V is blue and 0V is blue with white tracer. Ground/Earth is green with yellow tracer. Sensors are brown, blue, black, white, 24V, 0V, Signal, Signal 2.
Military and aerospace is all white. There are so many wires in current gen aircraft that it's impractical to have unique colors for wires.
The general name for "Mil-spec" connectors are called "cylindrical" connectors. Auto-sport connectors are just a brand name from Deutsch, they are all derived from MIL-C-38999. Our go-to for cylindrical connectors are Amphenol. If the cylindrical connector uses the MIL-C standard than pretty much all the contacts are interchangeable.
I love your wiring videos, they just make sense. For example, if I understand this right if you were going to wire up a simple ignition coil (I'm familiar with Honda's wiring layout) you need 12v power, signal and ground. So you would do Red as your 12v power, yellow for 5v signal power, and let's say blue for ground. It makes total sense in my 🧠
Aviation grade stuff. Aircrafts have these connectors everywhere since beginning. And jet engines harnesses? Everything is in DR25. I checked the other day actually at work :D Basically everything what is in autosport came from aviation. V-clamps, intercooler piping clamps you have and so on and so on
I'm so glad this video came out before I get started on my 2jz rx8 wiring harness
In cold war lobby, see an hour and a half video from Daddy Dahm.
Later boy's, got business to attend to.
This is the content i live for!
I’ve learn a lot from you rob. Recently wired my car with all rywire stuff but this video convinced me to go back and do the little things a bit better, the car should’ve burnt down with the wiring it had before so no sense in replacing their bad work with more bad work lol
Another IT carry-over 'life hack' you can use to save money and time is to get yourself a roll of velcro tape to use before you're ready to permanently set your bundles. Use the removable and reusable velcro wrap until the very end - THEN switch to zip-ties to permanently mount them.
