I have a cut wiring harness for a 1JZ out of a soarer and I need wiring that'll work in an 89 supra. What would be the best way to get wiring that'll work?

Depends how confident you are in your ability. Personally, I would do it all myself, but some people seem to be scared of wires.
annoyingrob gave you a good site, here is another with a site. becareful because the ECU pinout diagram is for a supra ECU.

Another thing to keep in mind when working on Toyotas. Pins may change, but colors are largely the same.
eg: a big black/white wire is going to be a starter signal on prety much any toyota. Makes wiring almost "match the colors"

I have the part of the wiring that hooks up all over the engine but then it ends and I have a supra ECU. What would be my first step? I've done no wiring before but I've been taught a bunch of it in school so I'm willing to try it but a walk through would be great!
I had a similar issue. My harness came with the body plugs cut and no where to be found. There are wires in there that look the same and just makes more questions than answers. I finished about 80% of it and then had to give up. I bought a 1JZ harness complete and uncut for $350 and it took me about 6 hours to convert it. Took me awhile to find one, but I did find one! Keep looking!
I didnt really think it was that difficult to build my own 2j harness for my GTE AEM install on a GE motor. I just traced out every line. Are you going standalone?
If not, I would solder the connections and use shrink tube on a portion of the harness that doesnt bend and flex. Be sure to stagger the connections so that you dont have a big ball of thickness.
If so, you could probably just use a 2jzge harness with a 2j AEM and wire it up accordingly. Or, you could get a stinger and use that harness.

well the information is out there, you can use a 2jz ecu but you lose the RPM limit you had on your 1j.. it will now have the lower rpm limit. if you want to wire it yourself i suggest extending the wire from the plug so you wont have to worry about old solder down the road messing up signals and whatnot.

tlo is correct.
Look at this thread I made....http://www.supramania.com/forums/showthread.php?t=43888
You got it
P.S. I had my thread stickied so we hopefully (yea right) won't have any more of these threads made.
