LS harness pin out 4l80e so I’ve been doing my wiring clean up on my lq4 and I’ve ran into a little bit of a problem. I plan on running a 4l80e but the harness I got with the motor is not the original harness. A lot of things hook up besides the drive by wire. I plan on using the drive by cable and the harness already has the plugs for it. But when someone cut the harness out of the donor they cut the wires for the trans. Now I know I can get a plug for the 4l80e that’s not a problem. By my question is how do I go about keeping the right wires for the trans? From lt1swaps.com I’ve depinned everything and left the auto trans stuff it said to keep but my harness had a extra plug near the pcm that I don’t have a clue what it goes to. I have the c2 plug the c100 plug and the other main one. But this plug is a 16 pin grey plug and I haven’t found a diagram that shows what it is and how to go about getting rid of it. Maybe electronic ride control?? Pin 38 which is the pick/white wire goes to it and I’ve already depinned it from the pcm. Just a really confusing thing I can’t seem to figure out. If anyone would like to help or direct me to where I can figure it all out.

If you create an account at autozone.com they actually have wiring schematics for most of the early 2000s vehicles. Maybe start by going there and looking at the silverados with the 6.0 in them or check the escalades. I used the site a lot when i did my swap which was an lq4 out of an express van.
