whatnow123 Posted July 4, 2014 Share Posted July 4, 2014 (edited) Hey Everyone, I'm at a loss now on my build, I pulled the positive battery cable out to hook up the starter and there is a plug on one side and I don't have the connection on my harness and I don't remember where it went.Did this connection plug into the wiring harness for the fuel injection which is now long gone with the engine? Also, is this the plug that sends juice to the battery from the alt? If it is, can I just run a "hot" from the alternator to the battery as I found in the ford wiring of the alt via this plug? ?? It's a 1992 mustang internally regulated alternator. Thanks in advance as I'm hoping to fire it up this weekend! (I do have the alternator wired up already with the white/red lined wires that feed to the fusable links "links".

NewZed Posted July 4, 2014 Share Posted July 4, 2014 That's the power wire to the 1978 EFI system, with the fusible link intact. There would be a red wire with the opposing white connection on it from your harness, to plug in to, with the original EFI harness. By the way, you didn't mention anything at all about a different engine in the car, so I just guessed based on your other statements.
