Need some help with the wiring of a 3G alt into my 84 F150 4.9. Off the back of the old alt are 3 wires, 1 black/orange & 1 black that run to the external regulator. And a yellow wire that I believe goes to the Engine Control Module.
I know to run batt. cable over to the batt. or starter solenoid with a mega fuse in line, but what about the other connections on the back of the 3G? It has a built in regulator. And what do I do with the old wires that are still connected at the other end?
