Electrical Rear Defrost - '87 - Volts, Amps: Yes. Deice: No.

I have a 1987-1989 Mustang wiring diagram manual somewhere. Problem is it's likely stuffed in a storage unit right now as I just sold my house. I'll see if I can dig up a copy online that may show what you need to know.


EDIT:

I have the 1988 version, but this manual has been very valuable to me for troubleshooting and deciphering the wiring in my car

Cheaper ones available...but kinda tattered.

I'd pull out mine if I could
