ok I need help. I started on my wiring harness and I'm getting wires that don't match up quite right. I have an 89 which is the crossover and it is a pain to find the right wiring diagrams. Has anyone done a successful swap in an 89 turbo, with ABS and it has TEMS. If there is anyone who can give me some pics of their wiring so I can see where I am at or even give me some diagrams. Also I have 2 thick guage black wires that have been cut and I'm trying to figure out where they go. Someone told me they thought they were to the alternator but idk. Please help!

First off, search. There is plenty of info in the site.

Second, those are the cables for the alternator that go to the engine junction block for charging and what not.

I tried all of the stuff from 1jzgte.com and have all the pdf files and I've go some of the wiring done its just that I found some other pdf files in anouther forum and they wouldnt open for me. I'm trying to see if I have a Soarer or Chaser model of the 1jz. It has the hydrofan but some of the wire colors differ from the diagrams I have. And for the black wires do you know of any diagrams to show me where exactly they go. I'm sorry but I'm still kinda a noob at this stuff and still learning.

The alternator output needs to go over to the drivers side of the car to the origional 7m alternator wire that extends from under the fuse box.
