Is the wiring harness from the computer out through the engine compartment the same from 90 to 91? I imagine they would work exactly the same, both had air bags , mass air etc. If anybody knows that it will not work the same please let me know. Or if it is a little different, what wiring changes would need to be made? Thanks in advance for any help. (car is 91, wiring harness i want to put in is a 90, both GT)

Not al 90-93 are the same... On the plug(s) behind the driverside strut tower some have 1 plug and some have 2 plugs... I have a 90GT harness that we first tried to put in a 87LX but it wouldn't work. Then we tried to put it in a friends 90GT but he only had one plug... :confused:
