I HAVE BEEN LOOKIN FOR A WEEK TO GET A DAMN 87 MUSTANG 5.0 ( GRAY AND BLACK) 8 PIN CONNECTORS and (Green 8 PIN CONNECTOR by the ECU) DIAGRAM. WHY DOES THIS NOT EXSIST ON ANY SITE OR IN ANY BOOK I CAN FIND The connectors are the 2 close to the test plug toward the end of the wireharness next to the self tester at the end of the engine harness.. ALL I FIND ARE THE 88-93 DIAGRAMS THAT DO NOT HELP ME FIX MY PROBLEM ;( THERE CONNECTORS ARE BLACK AND BROWN AND I DONT THINK ARE THE SAME WIRING SET UP AS THE 87 MUSTANG 5.0. I NEED THIS BECAUSE I HAVE PUT THE 5.0 ENGINE, EEC HARNESS AND ECU WITH 5 SPEED TRANS IN MY 96 N/A 300ZX. If i dont get a reply soon i may have to do wire by wire testing and hope to get lucky or run new ones to each point. HATE TO because they are already there. I just dont know which is which.

I had similar problem with 87 merc grand marquis 5.0l aod trans swapping it in to 77 f-150 and the only solution I found was giving the ford dealership in my area a ring and they allowed me to make copies of thier original tech manual. I'd try there. If I still had them I'd send them but I don't sorry.
