Pretty sure your gonna need a 91-94 wiring harness and maybe possibly ECU also. Someone that has done this better tackle this one. Im pretty sure though your gonna need the harness from a 91-94 car.

I'm not and authority on this issue, but from the sounds of it, it sounds like you might need to cut off some of the connections and sodder on ones from a 90 harness....
BUT!, i'm pretty sure that you shouldn't have to do anything to the wiring harness. 90 and 91's are pretty interchangeable except what spy was mentioning about the ecu needing to swap two pins. -------------------- game over.

There are a lot of plugs that are different on the 90's from the rest of the years. For it not to look like a hack job, you'll need to either swap the harness out, or (probably easier) swap out the Throttle body, Coil pack, and CAS. I think those are the only things different.... (been too long, can't remember for sure...
 )

I had to swap the entire harness to put a 92 engine (electronically the same as 91) in my 90 chassis. Even then some of the plugs will not match up. You'll have to do some splicing and soldering. Good luck!

If I remember right there were two plugs that didn't match up for me. One in the passenger footwell and one near the ECU (not one of ECU plugs). I just matched the wires color for color and broke out the soldering iron.
