one wire, internally regulated. what are you running for one? electric fuel pump, dual fans, a/c and lights. stock stereo, basically the stock dakota setup minus the computer. thinking about the mopar performance chrome box for ignition. no other electric.

75 amp dual pulley too small?
run the one wire to the positive side of the starter relay?
what should i source the voltage supply from, for the volts gauge?

thanks, and stuff.
