I'm working on Re-wiring my 78 brat.I will use an EJ alternator with the ej22 until I find a better alternator.However that is not my question.On the 78 Brat it has a yellow wire and a black/white wire at the alternator.Correct me if I am wrong but the yellow wire should be switched 12V,while the black/white wire should be 12V constant at the most electrically distant location.
First of all am I correct in the function of each wire or do I have them backwards?
Secondly I will be running the battery in the bed behind the cab on the right corner,So I am wondering where the most electrically distant location would be.
Should I run the black/white wire to the battery or should I find a 12V constant wire in the main harness after the fuse box?Finally of the original wires for the external regulator I have a 12V constant white wire(I would connect the yellow wire to it but it wouldn't be very far from where the output on the alternator would be), a white/red wire, and a large black/yellow wire.Which of those wires can provide the 12V switched power that the alternator needs?
Oh yea,I wont be running the factory instrument cluster so the switched power wont be coming from the charge light, because the instrument cluster and most of its assorted wiring wont be there.I'm running aftermarket gauges and only keeping the left/right indicators as well as the high beam light.
