Wireing harness?

[89ghost]

Can i use a wireing harness out of a 89 gt and put it in a 90 coupe? HEEELP PLEASE!!!

I would say yes. Might have some extra length wires, but should fit in there.

Might run into an issue if one is fuel injected and one has a carb.

Well ive been doing some research and everybody is saying i cant use it bc the airbag and fuel pump relay under the driverside seat
90has to use a 90 harness and 91 is a (stand alone) system whatever that means and 92 and 93 can be used only on 92 and 93. My question now is what do i look for before i buy the new harness to make sure i get the propper harness.

x2. They're not that expensive, they're better than stock, and they're made in Texas (RG).

Your 89' Comp is actually quite rare. In clean working order, you'll be able to get more than you'd expect for it.
