Sorry, Mr V.- on looking in my library, I found three separate 'official' wiring diagrams: 6/15/'72, 9/'72 and 11/'73, but none for the post-Ford cars from the '80s. The POCA store may be working on a late-model wiring diagram for the GT-5 and /'5-S cars, for release in 2001. Try e-mailing the POCA store manager at
. Good luck.
