So…a little more about this conversion. Napa sells two necessary harnesses if yours are missing. The one from the alternator and the one from the voltage regulator. The only glitch we encountered with these is that the two wire alternator harness had the blue field wire and the black ground wire reversed in the little plastic plug, so we switched these prior to installation so that we could keep the colors making sense. Essentially, we then wired blue voltage reg. wire to the blue field wire on the gen, black ground wire to the black ground on the gen. Red power wire to the ignition to acuate the red “GEN” idiot light on the dash (we used a 10 ceramic resistor in between at the suggestion of the blog we read), and brown to existing brown wire. I learned how to solder and use shrink wrap well! It works great. Consistent 13.5-14.5 Voltage while running. I also found a product you can get at any parts store called “liquid electrical tape” that brushes on and forms a soft barrier around the soldered joint in case you forgot the shrink wrap or didn’t want to damage the joint by twisting tape around it. It works very well.
