Coming from an electronics background, I appreciate you advising to put the heartshrink on first. Reason alot of people end up using tape.
If you only want LED reverse lights just cut in to the reverse light wiring in the tail lights. It's a really easy fix without having to chase around the engine bay and dash. It's only 2 wires, just keep positive to positive and negative to negative if daisy chaining a couple of LEDs as they draw very little power.
And how would I do that if I have a plug sort of thing for my light bar instead of just wires?
@@jacksonmorgan8943cut the plug off and then you'll just have wires...
Legally you'll need a switch. And you'll need to determine whether your wire and fuse are beefy enough for the extra current. Caveat emptor.
I've started putting a plastic splint in with any joined wire or soldered connector. I cut little 2 to 3 mm wide strips off a PET drink bottle and slip one or two of those inside the heat shrink. They won't melt and they add a bit of rigidity to the join which makes them longer lasting.
Nice work well done and explained well.
Hi, great video. Wondering what the possibility is of having the lights wired as in the video, but also wired to a dual battery set up with on/off switch in the rear of the vehicle.
I have the kings switch panel and looking at using one of the switches in it for these lights?
Your gromet on the firewall has been abused Cah.
This is the best way to install additional reverse lights.
G'day Tyson,
Yep, the grommet probably needs to be replaced - but it's Brenno's DMAX so I'll leave that up to him haha.
Thanks for the comment too - I figure it's also the best way as it's got a separate circuit, plus it's easy to upgrade lights if need be!
Cheers,
Cahn
I’ll pay my Auto Electrician thank you .
Thanks for saying Deutsch properly - amazing how many can't :)
Thanks for details video
Would wiring up 3" work lights on a roof rack be exactly the same as what you have done with the reverse lights
Sir, you are amazing. Thank you !
You are very welcome
very nice.
Fantastic video 😀

Nice work! Looks the goods 👍
Good stuff!
Why do you need to run a wiring loom & a relay & not just wire it straight from the reverse lights?
I'm guessing the law requires them to be switchable from the dash.
Really wishing he used the same switch as the other 2
But good video
Good vid cheers mate!
Where does the red triger wire go? He explainded where it goes at the rear of the vehicle but What does it go to at the front of the vehicle.???

Best of wiring a 3 way rocker switch, so you can turn them permanently on, off and come on with reverse.
After that too let me know
could you just wire them straight up to the reverse lights ?
Amazing video. Could you do a video about winch cradles. I have a hilix with a genuine bull bar but unsure how to mount a dominator winch to it. Cheers
Hey David, I'll pencil it in and see if I can do a new Domin8r winch install video, showing how to use a winch cradle as part of it!

Thanks for the detailed and well-paced instructions- will 10 amp wire suffice for 60w led units and a 15A fuse at the battery before the relay? - John n SA
10 amp wire 10 amp or less fuse
Go less than 10 Amp for the fuse, if you go 10 10 the wire could burn before the fuse trips.
@@jackshen9235 ok thanks Jack - April to June is the Hilux (pre-Covid) canopy build and then head off to TAS then trek up to FNQ - kitting out with Redard, Engel, Lithium, Renogy, LED lighting and all my own wiring with fuses everywhere - took 12 mths to get a 23 Zero Stealth but will be worth every $ - had to modify KINGS awning eyelet hole tearing (common problem for both of these) at awning outside corners using a ‘sandwich’ of metal plates along the thin channel so much better now and the awning material is very waterproof and provides great shade - John in SA
So I hooked up 4 9" spotties with ur harness but I had to extend the plugs for the spotties bcoz they r on the roof so I cut them an added about 2m of 15amp twin core wire an hooked them back up but they were working before I cut the wires but not now is my 15amp wire to small for the job only bigger size I can go is 50amp but that seems to big
How did you join wire to reverse wire.. Some how you did a three way, is that correct?
Could you just run a power wire from the battery and then power from the reversing lights to a relay to switch the back up lights?
Yes but you'd still need the Dutch plugs to fit the lights and a switch, by the time you buy those two things for 20 bucks you much as well buy the whole harness for 30
Hi. Seeing the l.e.d lamp only draw 2 amps can I just link a l.e.d load resistor onto the lamp then couple it to my current existing factory reverse lamp on my 2012 Nissan Navara D40 diesel?, I'm wanting to just have it on when reversing only as I don't want to run it thru a switch.
Cheers Carl
So what do you do with the black wire on the trigger cable ?? Connect it to ground ay ?
9:20
There's not technically a negative trigger wire. The positive trigger wire goes from the reverse light input to pin 85 (or 86) on your relay. the negative that's along side it is to earth the LED in the switch so you don't need to connect it, but I show it at 9:20 - I just shorten, add a ring terminal and earth it to the battery.
Cheers,
Cahn
If my switch has only 2 wires (blue and black) but is a 4 pin on/off rocker, and I have done everything shown in the video, why is it not working? The only other difference is that I have a small round 7 pin which has the black wire as the constant and the reverse lights. Also, I noticed that the black trailer ground wire is joined to the positive terminal and has an inline fuse. Would having 2 separate inline fuses (for trailer lights and LED lights) both running from the positive battery terminal make a difference to the power received by the trailer reverse/constant wire? And why have they made the reverse wire a constant wire? Wouldn't that mean that the reverse lights would be on all the time? Should I do something different? Cheers Tania
I'll have to give it a go I'll let ya know if my car burns to the ground😂😂
Did it burn to the ground?? :D

Gday Cahn,
Am I right in thinking that the way the switch is wired, the lights wont be able to be turned on/off independently of the reverse signal being activated?
Hey Sean,
That’s correct but you could have them switched independently. A good idea would be to have a 3 position switch, so you could have ON, OFF, and ON when reverse lights are on.
You could just use 12V power from the battery as the trigger for the ON position of the switch so the reverse light doesn’t need to be on. I’d recommend a fuse if you go that way, and keep in mind you can flatten your battery, plus you’ll need to check the legality of having rear facing lights that you can switch.
Cheers,
Cahn
What awg wire is the black and red wire used please?
What would you use as a trigger if you wanted to run the lights switched seperate to the reverse lights? Just tap into accessories?
Hi Ben,
Yes you could or you could just use 12V power from the battery as the trigger so the vehicle doesn’t need to be on. I’d recommend a fuse if you go that way, and keep in mind you can flatten your battery.

Just check legality as well of course.

@@4wdsupacentreAu I've tried this but didn't work, I cut trigger plug off and crimped terminals onto the wire along with a fuse but still had no trigger. What do I need to do differently?
I'm probably overthinking this, I have small work lights mounted on the side of my work car. If I run the signal wire straight to B+ and connect the rest as usual, I should be able to toggle them on/off when the vehicle isn't even on correct? Also because its only signal for the relay, while the switch is in the off position it shouldn't flatten the battery at all? Anyone confirm if that's right?
Can you add more lights using the one wiring harness or would you need a harness for each set?
Also would like to know
What changes would be needed to suit a three way on-off-on switch so it works on reverse light and by independent switching. Is the wiring harness usable in that case?
Looking for an answer to this also
Sorry I've taken so long to reply here.
What you'd have to do is replace the switch with a 3 way switch obviously (probably a DPDT), use the same method for the trigger if you want the reverse lights to work and then on the third position of the switch you'd need to have a constant power source into the switch and then make the output of that third position linked to the trigger output from the switch (white wire) or run another independent trigger to the same pin on the relay
I might do a video on this idea too!
Cheers,
Cahn
@@4wdsupacentreAu That would be a great video as a part 2 option to this video
@@4wdsupacentreAu Have you done a video regarding the DPDT switch? Having a hard time figuring it out.
Would it be a good idea to install a second crank battery to run lights, spotlights, winch, etc instead of just using the one battery?
Yeah that’s what I do but I just use a little car battery so everything doesn’t drain my main battery
Where do I find the 12 awg and 20 wire ?
What is the 20 awg wire for
Where can you buy the 12 AWG wiring from?
Hi Stewy, I just google it and can see that Jaycar, repco and bunnings come up as top results. You can also try eBay or Amazon.

So I installed these today however when i shift into reverse, the led light bars come on but they flicker. What have i done wrong?
Check the connects
Yeah all sorted, cheers
Hey mate, done this and I'm stumped to find im having an issue, tapped into the reverse lights and now when ever I flick my rocker switch the reverse lights go dim, the aux light doesn't come on. Any ideas what's going on in my case??
Any bad earths?
Can you show a video how to put side working lights on your ute or a tray light
Absolutely can do - but if you wanted to have a crack yourself, you'd just need to connect the red trigger wire (that I trimmed) and black earth wire directly to the battery.
Add an inline fuse for the red trigger wire near the battery and you're laughing!
It means the included switch will turn the lights on and off without needing another input (like the reverse lights in this case).
Finally, just check the regulations for your area to do with having lights that can be turned on permanently, on your vehicle!
Cheers,
Cahn
@@4wdsupacentreAu thanks
video is good. i bought reverse light . could you please let me know what are the silicone and spray used. also the video of wiring (cutting and joining to fast) its possible to explain which wire need to be cutt and extend. i bought kings drive light cable. thanks
Any silicon will work but I used Sika 221 as I had some already!
Spray paint was just a satin black enamel
Depending on your vehicle and the distance between your relay and reverse lights you may need to extend the red and black wires with the deutsch plugs for the lights, and the single red wire for the trigger that connects to your factory reverse light wiring.
(On the Kings harness the trigger wire is the red wire with the white plug that I cut during the video)
Cheers
Cahn
Your questions are on a very basic level. If you don't get this then I'd get help when doing things to your vehicle, then learn a bit on the job.
Also, his not going to go into great depth in every step he is doing. If you have questions that aren't explained enough in a video, just youtube that question for an in-depth answer on your questions...
Hi mate how would I go about wiring my 2 up for camping on my canopy? What would I use as a trigger wire?
Just run power through your on/off switch to a relay. Then the direct power for the lights through the same relay to the lights.
@@enjay8950 I tried this, but the lights are not as bright as they are supposed to be 😐, not sure what I've done wrong. 🤷🏻♂️
Mad vid, if I wanted to just put it on a switch and not on the reverse cable. How would I do that
just install it as a normal wiring harness without hooking into your factory reversing lights
@@jordanspurling772 The trigger wire still has to go somewhere though or it won't work
@@NitrosDen I figured it out I just put the trigger wire to the battery
Is there a way to make them only come on when the lights are on and in reverse?
You will need 2 relays. To do this, run a trigger wire from the headlights to the first relay.(Which therefore switches the relay on when headlights come on) Then add a second relay to control the reverse lights, and pull the trigger for that relay from the first relay. So when the first relay receives power from the headlights it then supplies power to the second relay. which then supplies power to the reverse lights.
So power runs through the first relay (when headlights on) and into the second relay, and then into the reverse lights. The headlights controlling the first relay will switch on the second relay therefore sending power to second relay.
Just simple 4 pole normally open relay.
It's a bit hard to explain but easy to draw up the circuit for it. I hope it makes some sense from what i've written. If you type into youtube "moss motors how to wire relays" There is a 3 minute video which is very good.
That’s for that detailed reply
How can you have the lights triggered by the reverse light plus on the switch it self?
Through relays! They're magic bits of kit.
@@enjay8950 Gee great explanation to their question

Is someone sees this, I need help. I got the kings 3 inch work lights and wired them straight into my reverse lights (hallogen) I tested with one connected up. Works perfectly, when I have both wired up (one to each side) the both turn on for about 3 seconds before I lose all my rever lights. Nothing gets hot.. wiring is fine but only when I have both wired up they turn off after 3 seconds. Am I missing something or should I wire it a different way?
If they're wired straight up you could be overloading your vehicle's reverse wiring (particularly in a CANBUS system)
that's why I'd always recommend using the reverse lights as a trigger for a separately powered relay that then powers the LED lights.
Cheers,
Cahn
@@4wdsupacentreAu is it possible to run this without the switch? It comes with a white blue and black cable connected to the switch, should I cut and solder these together for a constant on feed to the relay?
Great video but I’ll leave it to the professionals.
or you could just tap into ur reverse light wire.
Hey mate, I did tap into the reverse light wire - as a trigger for the relay. There are plenty of ways to set up extra reverse lights and this is just one of them.
But if you mean run lights directly off it without a fuse and relay... go ahead if that’s how you want to do it, it’s your vehicle! Just check local rules in case you need a switch to be able to turn them off if need be!
Doing it the way in the video means you can run some pretty powerful lights, completely on their own circuit, so you have separate fuses and it’s safer / won’t overload your factory wiring.
Again this is one way to do it, but if anyone has their own ideas and they’re happy to give them a go, then go for it!
Cheers,
Cahn
@@reeceg6058 how would an automatic be different for this setup?
isnt that illegal because it can blind others
No, it’s hooked up to the reverse light wiring so can only come on when the vehicle is in reverse!
Lights can't blind people.
