Need Help! Need Engine/lights wiring harness info/ideas!

Yeah, that's what I was thinking.

Any model that uses this same basic harness would hopefully be about the same. Just so the block is the same with some good wiring coming out of it. If I have to swap some connectors, lengthen some wires and whatnot, that's fine.

The car is NOT getting the original engine/trans or anything else, so I can use what I need from whatever harness or modify to as needed to work, but being the exact wiring/options the car came with is unimportant in this case. I just need some wiring to work with.

Thanks for anything anyone can do to help!

And yeah, this wasn't the only completely stupid thing done to the car, but it is the only thing right now keeping me from getting a new drivetrain going in it.
