i have a 62 and all the diagrams online are 64 and up. none of them are the same as mine. i need to know how to wire mine for a internally regulated alternator.

also-- i have a white wire coming out of my ignition switch thats labeled as "GRD" ground, but, the only white wire coming out of the harness in that area is HOT....??

also-- in the same spot there is 2 green wires going into the harness, no idea what they connect to?
