- Hey guys, in this video I show you how to easily replace the pins or terminals on the Molex plugs on modern ECMs.
Here is a link to the extractor tool I use. amzn.to/2VsMaH7
This is the plug if you need one. amzn.to/2JO5ts8
These are the terminals I used. amzn.to/2YyoXoT
Here is a great manual on these connectors!

I'll have a much more detailed list of part numbers when I replace the entire harness.
This video saved my friend in Az that bought my buggy. His ecm lock plastic failed and he just went to pull a part for a new housing to re-pin to. Thanks Mr Doug
Glad it helped him out. 👍
Thank you so much!!! I've been trying to recover a few pins for months, I've almost given up hope. Thanks, man!!
I'm glad this helped you out. Thanks for letting me know.
Very informative. I’m about to replacement the 10 pin connector on my son’s 2008 Silverado. The locking lever broke and I was able to find a replacement on LS wiring.
Thanks for posting this video up. This was exactly what I was looking for.
you prolly dont care but if you guys are stoned like me during the covid times then you can watch all the new movies on instaflixxer. Have been streaming with my gf lately xD
@Blake Archie definitely, I've been using instaflixxer for since november myself :)
@Blake Archie Yea, I have been using InstaFlixxer for since december myself =)
Thank you Great help. Also wanted you to know that you can pop out that blue insert that you raised up 5mm by prying on the other two sides once you raise it 5 mms. This way you can use a jeweler's screwdriver to release the clamps. Will save the $60+ dollars for the . tool. I don't plan on doing this again
Thanks for the info!
You can actually take that plastic cover off and then pull the pin out from the bottom side
thank you so much for the video. im going to use it to install efans on a truck that has a clutch fan. i need to add two pins into the plug then its just programing the truck to turn on the fans.
Figured it would really help some people out. Good luck with the project. 👍
GM weatherpack terminals will release with a small paper clip as well did it for years as a GM dealership line tech
I suppose that might work on this if it's a really small paper clip. The wire on this tool is so thin it's almost like a needle. And at that it's a snug fit. But if that works it's a great tip! Thanks.
Thanks Doug for your videos awesome information 😀
No problem 👍 Thanks for the comment.
Good effort well done
Thanks a lot 👍
My blue plug won’t go back in flush after changing the ecm like the connector won’t lock into place
Thanks brother! Big help!
Glad it helped!
Thank you, so much good
Welcome 😊
Great video. Thanks for sharing.
Thanks buddy!
Master's work
Thanks bud!
this is very informative. how would you know if you had a loose connection to where the pin on the ecm is not fitting snug into the female hole that the wire is crimped onto?
That would be really hard to tell. But first make sure all the pins out of the ECM are perfectly straight. Then inspect the plug. I would then replace any connectors that You thought you were having issues with just to be sure.
You can't really test those connections with a meter as they go into the ECM. So you'll need to basically do it visually.
If you have HP Tuners it would help to connect and read data then wiggle the plug around to see if any sensors go in or out.
like to know more about the stock sending level set up, not sure if you made a video on it? thanks for all your helpful tips.
Hello Ed,
About half way through this video I go over some of the sending unit/fuel pump installation. czcams.com/video/p5tNM8NqBWc/video.html
I ran two units for backup. If one fails on the trail I would need to swap the fuel line and the electrical plug. Then I should be back on my way.
Any questions beyond that let me know.
Thanks for this vid, ecotec swapped my Miata and couldn't figure out how to repin for a tach wire
What wire are you using for a tach? I've never been able to find that out.
@@DougBugBuilder from what I've found out from wiring diagrams, and from talking to others on forums, it's terminals 24&25 on connector c1 (from factory they are not used and a plug is in the termination slot). Terminate and Splice both together, then T off your splice to the tach signal wire. Another forum user I talked to said it worked for his setup (06-07 e67 ECM)
@@ruthlesschoy So take 24 and 25 and splice them together and run it to the tach as a signal wire. Interesting? Please let me know if it works so I can give it a go. Thanks. Mine is the E67 so I'm really interested to see if it works.
@@DougBugBuilder yeah signal being your ingition coil wire or ignitor wire to the tach. I'll send ya a message or reply here and let ya know once I do it!
@@DougBugBuilder I can confirm it works. Terminal 25 is tach signal but doesn't work without a pull up resistor, just so happens that terminal 24 is a resistor, so I spliced both and ran it to tach and it works! Just needs to be dialed in with hp tuner
Good tip . great video demo . wires are the hardest part of the build for Me I want to change my 2332cc VW motor . I like the eco Chevy 200 hp that you went with . but the Honda V 6 has 300 hp . what do you Think.?
The Ecotec is a great motor and it scoots along nice! But it you want wheel spinning torque go with the V6 Honda. But you'll need a good transaxle to back it up!
Yeah very helpful, thanks!
You Bet!
nice tip.
Thanks!
Is the tool solid or a tube? What is its approximate diameter?
Where can I get an ECM pinout list like your's for a 2015 Sonic LX 1.8L??
You should check with Holley about there holley terminator when you redo the harness. You can check it out on Sloppy mechanics CZcams they're using them on the Chevy LS engine if you could use it on yours it might give you some neat options
Anyone have the part number for the metal pins required for an NNBS Silverado ecu?
My problem is my 1,3,5 plugs are firing my 2,4,6, is not im.thinking it's my ecu bc I changed the plugs and coils my code reader say that the 2 4 6 is misfiring. I took out one of my plugs and coil put it up against metal there was no spark I looked at so many videos on it. But there wasn't too much on it. So I came across yours im.hoping that's the problem I'm having. I've got a 2008 saturn outlook came you give me some pointers on what to try (thank you)
First thing I would check is that those coils are getting voltage. If they are then I would trace down the signal wire and make sure it is connected to the correct pin on the ECU.
Hello Sir, what size terminal pin did you use for that wire? 1.5, 1.7, or 2.4?
Not sure I understand the question. Do you mean on the terminal I used, or the tool?
@@DougBugBuilder, those ECU connector pins has a measurement spacing. The brand that wasn't Molex, had those measurements. I was trying to order the right ones on Amazon. But, I recall you left a little list of items ya ordered off Amazon. So, I ordered the molex MX64 series 33467.
@@patsuddarth1093 Ok, looks like Amazon doesn't offer them anymore. If you email me at dougbugbuilder@gmail.com and I'll send you a parts list I have of the connectors and pins. That might help you out.
My conector broken shift hold arm what i do😢
You probably need to replace the connector. It can be done, but you need to be careful to get everything back in the right spots.
Great video. Where did you find the ECM pinout? I've been looking for a pinout for my ecn without luck!
Check this video go to the 4 minute mark. This is where I got all the info for my EcoTec.

That tool looks great - but....at $70.00 for the tool, isn't there a less expensive tool available? Is there any way you could reveal what the outside diameter is for this tool is and is it a hollow tube solid?
I have lots of terminal release tools, but without knowing what size this Molex tool is or if it is solid round, or a round tube - (or some other shape), I don't know if I have the proper size.
If you could share the measurement and whether this Molex tool is solid, or round tube, that would be great!
The tool is solid and it is .026" in diameter. If you found a very small drill bit that size it should work too.
What are the pins size? (in mm)
Any idea where to get those plastic red slide tabs on the pcm connector ?
I got my parts from "Mouser Electronics". I don't have the specific part number for that part. But here is my parts list for my harness. It might get you really close.

v good video i m strggling to get in 1939938 into te electronics 60 pin connector
Did the B1 deserve a try? any good?
? Sorry, I'm not sure what you're referencing.
You can’t just removed the entire blue connector from the black housing and out the blue connector into a different black housing
