My buddy swapped a 94ish LT1 in his FJ 40, and has an aftermarket harness for the wiring. He cant seem to get the alternator to charge the battery, so we are looking for a little advise on where to wire these things to. None of the wiring diagrams have the same color wires as what he has. The alternator plug only has 3 female connectors, but the alternator has 4 male prongs...? The alternator is of the hi-amp option, or so he was told by the wrecker he bought it from. The wire labels for the alt plug (from top largest wire down in the picture) are: S F L P (P doesn't have a wire, but there is a prong in the alternator for one). Anyone know how to wire this bitch?
