Chassis wiring diagrams

[Blown347]

Here are a very good set of wiring diagrams. they are specific to a 1990, and include everything for a coupe/hatch, convertible and even 2.3L specific wiring.

(I wired my entire car front to back from scratch with these, so they really do have everything you need!)

How much of a difference is the between the 89 & 90 gt other than airbag? Worse case scenario, I'll turn my car into a 87/90 GT...winter project anyone?

Factory 1989 Ford Wiring diagrams. They are large but worth it.
