Im currently trying to put a 1ggte in my 89' Supra and im having issues with the wiring harness
If anyone can tell me how to wire up the harness to where the engine would start that would be much appreciated
Thanks.

Well, besides you posting this in the wrong section..........
If you don't have the 1G ECU, you are probably screwed, even if you could find the wiring diagram for the baby 7M 1G.

But that brings up the question: Why do you want to put a 2-liter engine econo engine into a 3500 pound car ?
I've seen the results of someone putting in an SR20DET, and the results were boring.
Extremely slow, and under powered, even with increased boost.
Just because someone gave you a useless engine, it is not a reason to use it.

Find a pinout to the ecu and give the ecu power, find the EFI relay for the fues box connector and supply power to that, connect the grounds and put 12 volts on the starter signal wire. Engine will run regardless if its in a car or not.
