Removing the harness
Alright, once again, I need a bit of clarification. I have started trying to get rid of my TBI harness, as I no longer have any use for it.
What wires (if any) can I cut up and which should I leave intact?
Also, there is a small black box right behind the drivers side wheel well, a bunch of wires are going into it, how would I take this out without cutting anything?

Re: Removing the harness
what are you doing for the lockup on the trans? you may also have issue with the vats system as well.
Otherwise, unplug the ecu, disconnect the c207 underneath the dash, and the complete passenger side harness can be removed as a whole.

Re: Removing the harness
You should consider leaving them in there. There's nothing anyone can see from inside the car. The entire wiring harness can be tucked in the fenderwell on the engine side completely out of sight. There's no desire from anyone to buy your TBI harness, so you can't make a buck off it, and there's no significant weight savings by removing it.
Leaving it in, you now have an almost endless supply of wires to utilize that already run from the cabin to the engine bay, with no water leakage, no entryway for bugs, mice, etc. And they come in real handy for running toggles to things like exterior lighting, fan switches, fog lights, aftermarket guages, manual switches for torque converter lockup, etc. I've made alot of use out of mine over the years. Something to think about.
The driver side harness you want to leave alone - that's all basics like guages, lights, etc. The pass side harness - that is ECM wiring and all that gets disconnected.

Re: Removing the harness
Ha, by removing it, I meant tucking it out of the way, not really cutting anything out. I had a feeling that I shouldn't tinker with the drivers side stuff, but it seems like everything is interconnected. I'll take another whack at it tomorrow morning, as I don't have to go to class.
I was also wary about anything around where the battery is placed.

Re: Removing the harness
There are a couple of wires that run from the pass side harnes into the main harness that runs over the top of the bellhousing and come out by the driver harness 0 like fuel pump relay signal wire, the injector wires run about 1/2 way and exit into a small loom that runs over the intake, etc. - those you can cut on the pass side and just leave them tucked in the harness out of sight. Like I said, only a couple like that. The rest will all be easily seen on pass side.
Everything by the battery should remain in tact - those are all fusible links, wiring for the fan, and the weatherpack wire from the fuse by the battery that runs to the OPSU.

Re: Removing the harness
Thanks a lot man, I started figuring it out for the most part, as I'm not in a rush, I'll take my time with it to be sure not to mess anything up.
You guys helped a lot, thanks.
