Does anyone know what the wire in the 8-pin connector by the ecc connector go to (on the 87-93 mass air harness)? There are five wires in the connector and I *think* 2 of them are for the fuel pump...? I am doing a conversion from TBI to mass air. Anyone know? Thanks!

Let me guess your fuel pump wont turn on and your car wont start after the conversion?

I actualy broke out the Mustang manual and pinned out all the wires with an ohm meter. The two wires in question went to the fuel pump relay but I already had one in the trunk by the inerta switch (from the original cfi). I just spliced the wires from it into the harness. I was really freakin' surprised when, after all this research and cutting and splicing, it started up on the first try! Doing my homework finaly paid off. The throttle response on the sefi kicks butt!
