My donor vehicle is a 88GT and i'm about to do the wiring diet. I may have access to a 89GT Helms wiring diagram. How much different are the two years. I cant really think of any major changes that ford did between the two years. So would the 89 diagram work or at least be close enough that I could figure it out.

I have a Haynes manual with some wiring diagrams in the back and they are for 87-93 but they are in micro print :rolleyes: as a suppliment.

Think that the 89' diagram will work? Is there any change in some of the wire colors? etc..???

Hal,
I've been using a wiring diagram from a 91 mustang and the colors I refer to seem to correlate to many of the 88-93 harnesses.
The only way to find out is to get your hands dirty....

So long as the harness and schematics are both for a mas air and not speed density, you should be OK.

Thanks for the reply Ed.

I actually got a wiring diagram for a 89' from Ripsnake and started going through some of the circuits. So far everything is matching up with my 88' harness. (Which is converted to Mass Air)
