Well, all I know is the ecu has different plugs between the 88-89 years and the 90-92 years.

Undoubtebly, there are going to be some wiring differences between the '88 and the '92. I'd try to get as much as possible off of an earlier GT to get the whole thing thinking right. Your best bet is to have some electrical schematics by your side, otherwise you're going to run into problems. With patience and research, I'm sure you'll overcome this jam.

No man, a 91 wire harness will not work on the 88 GT moto, they are completely diff. 88-89 are the same computer and wire harness, 90-92 have the same computer and wire harness, so you have two diff. computers w/ wiring to choose from, but you can only use one, but by the looks of things, you going to need an 88 ECU, and the wiring complete to atleast mek it wuk. thas all i know, but good luck anyways.

I think the 90-92 harness will work on the 88 engine, provided you replace all of the sensors and equipment on the 88 engine with that from the 90-92. The engines themselves are probably identical.
