Fixing a 2nd gen 3sgte harness / preping for my swap, no, its not going in Jenns car, its going in MINE! ;) Options

[presure2]

so yea,
as most of ya know, we recently did up a 3rd gen swap for jim and as "payment" he gave me his 2nd gen setup.
as most of ya also know, this setup was originally RJB23's car, which was pretty much a mess from the day jim and shannon bought it.
Click me for details of that story

so once we got the 2nd gen motor up here, it has been sitting on a stand, waiting its turn.
i finally got around to getting the harness off, and am starting to get it cleaned, stripped, repaired, rerouted, rewrapped, and reloomed.
like everything else about the swap in that car, this engine harness was no diffrent, and in defense to the guy who did it (IIRC DGperformace did it) it did work, it was just routed and wrapped all crazy, and the ECU end basicly looked like a birds nest from people troubleshooting the ecu and wiring while it was in the car.
so i started tearing into it, and dustin came by last night and helped me get the interior plugs sorted out, since there was lots of "dead" (wires that go to nowhere) wires in the harness.
i also removed all the stuff i wont need or use, including all the ac stuff, TVIS, TVSV, ect.
once that was done, i went about cleaning and fixing any loose or broken wires, (there were a few, one of which wouldnt allow the car to start with the key...lmao) and rerouting and rewrapping it, getting it ready to be reloomed.
here are a few pics of how that is going.

first, the before. sorry for the blurry pic, its the only one i took..lol



this wire was in the harness that was routed behind the intake manifold, instead of inside of it, like it should be, and chaffed on the IM until it broke..just so happens this is the wire that tells the starter to crank. yes, jim, this really is why your car wouldnt start with the key! lmao



how the ECU side of the harness looks now:



and some of the leftovers:


and just for refrence, a pic of what a stock USDM 3s harness looks like, for an idea of what this one should look like when its done.


ill keep updating this thread and adding pics as i go along and continue with the project.

hey now that you bring it up. Wiring is the same for all swaps. Just different routes right. Just need to find the exact diagram.

What does it entail overall. moving the order of the pins in the plug, going from one place to another?

Can yo just post like a general of whts involved. Im assumming its just a basic rerouting of the wires. Just have to know where, right?

i would like to see that harness finished. Good job.

There is nothing basic about it.
You are trying to run an engine from a 5th gen, in your 6th gen car, so almost everything is different. But to give you an idea, you have to rewire the 3s harness to use the 5s fuse box and all of the plugs that interface with the rest of the car.

I might do a little write up (I've wanted to do one for like 4yrs now), but be warned ... this is really not something you should do if you don't know how to read wiring diagrams or are good at soldering/wiring. I'm usually a big supporter of people doing their own work, and learning about their car, but this is one area that you should probably outsource to someone like DrTweak.

Hahaha were all working on harness wtf. we should have had a harness party.

I'll bring the heat shrink and solder, you bring the hookers and coke.
