Trying to figure this out. I know it's not that complicated but I'm missing something. Everything I've read says take the brown wire for the generator light running from the firewall to the voltage regulator and run it to the #1 terminal on the alternator per the diagram below. I have a brown wire from my generator to regulator but I don't have a brown wire coming from my firewall...is a 62 color scheme different? Just trying to find the right wire for my gen light. The harness from my firewall has dark green (horn), a light green and a tan (headlight) and a large gauge red and smaller gauge red which both run to the same terminal on the voltage regulator. Can anybody help a wiring dummy out?
