I found It! no longer needed 07/08Wiring!

[ah.b.normal]

My life forces me to work in unconventional ways. I am researching how to convert a Automatic Engine wiring harness to Manual. The Automatic Engine Harness I have weeded apart leads me to think this is possible. Although made together, the ECM and the TCM wiring don't actually intermingle except for the speedo wires, grounds and power. I still have a few questions. I need an 07/08 manual engine harness. I could use wiring diagrams as well. But I find actually pulling harnesses apart and chasing wires very educational. I could benefit from pictures of all the harnesses laid out to show how they break down and couple together all the way to the BCM.(Light harness, fuel, emissions, rear light and interior wiring is not needed) DF's videos went through donor wiring removal rather quickly and didn't focus in on showing individual harness segments in their donor tear down. I've watched the thinning wiring videos, they are GREAT! but they are focused on that job. No junk yards nearby, I'm currently in Dubois, WY near Tetons National Park. A nice little town, accent on the little. (pop 6000) I've seen only one(1) local, a G5.(wrecked, no tag, not for sale, go away crazy old man!) I won't be near a big city that would have a junk yard until Albuquerque, NM, in early November. But I can send $ and receive mail! I found an engine harness on Ebay for about $100. I'm hoping someone's build leftovers can do me better, a slightly cut up example could still be useful so long as all of it's wires are there. Missing a few plug ends or the FI extension is no problem, location on the harness and wiring color is usually enough to ID terminals that are missing.

My understanding is that it's likely the 07 and earlier harness may be different from the 08 and later. The wiring diagrams I've seen posted on here are quite different anyway. This may be more the LSJ however. I have the 08-10 oem manuals and the harness are very similar for the all versions of the later models.

Alldata should have the wiring diagram you need.

Of course, thank you!, I'll check in to Alldata. I am always grateful for tips and participation.
But I am still looking for a actual wiring harness to experience. I am finding, in parts interchange data on ebay, that the 06-08 N/A versions{non SC/TC versions} didn't change much. My Victim is an 08 Automatic coupe and is resting comfortably 1522 miles away! I won't see it until March! (Maybe "Homesickness" = "Garagesickness"?!) I am trying to manage my time effectively by researching on systems I CAN access.
***********My victim is an Automatic and will probably first run as an automatic.(Unless a manual victim comes along!) The manual phase won't happen until after I have a running car as proof of concept/ prototype. (after I kill the auto box) I have the added advantage of knowing if this "project" goes Tango Uniform, I don't have re-sale value to worry about! I'll just scrap it.**********

************FYI The Cobalt owners manual states all Cobalts can be flat towed(all 4 wheels down) under 65mph, so long as they are in Neutral, key in ACC position and(for long trips) you pull the ACC fuse on the BCM, to cut battery draw. I would run an automatic for 20 min before towing any distance, to circulate the fluids, but that's my personal preference/opinion. This could save someone a tow bill? I once had to have my 97 Camaro/ 6 speed towed 3 miles to the house. That was in 06 and I'm still a little pissed about that. ARRRGH! $50 hook up, $2 a mile, depleting my beer money! I should have used a rope! *******

I don't trust EBAY parts interchange data.

Data was claimed to be Hollander Interchange. I guess we'll see?
