Ballast Resistor Wiring

the colors you are talking about were for the new connector when we re-wired the car. the basic wiring is the same no matter what color is used.

Sorry, I missed that. Good that the colors didn't change. I bet the factory wires weren't all 10 awg. That is only the 2 thick ammeter wires. BTW, a lot of people jumper across those to spare their dash (but disables ammeter). I am looking for a 100A diode to shunt it when >0.7 V (voltage drop I measure w/ alt full on), but not easy since those are big expensive suckers and need a heat sink. Most people change the ammeter to a voltmeter.
