you should get not using from painless fusebox the ELECT FAN wire and the ALTERNATOR/REGULATOR wire since those functions are unexistant on the stock setup. You can use them on any extra function you wish to give power from ACC section.

REMEMBER I DIDN'T DRAW THE STOCK CIGAR LIGHTER source. It can be spliced at ant batt fuse you want, If you want to keep the stock setup, it should be spliced together with the pink wire of the lights switch ( arriving to red traced black at new fusebox )

Parallel wires from alt and batt simply will arrive directly to ammeter studs, Nothing to do with the new fusebox
