I've replaced the generator in my '57 as part of an AC upgrade project. At that time I removed all of the wires from the voltage regulator and applied heat shrink to them. And I reused the wire from the A terminal for the GEN light from the alternator. Now I'm in the process of installing a new main wiring harness. My question at this point is as long as the main 12V lead from alternator is not connected to the voltage regulator, can I reattach the other wires that are included with the main wiring harness? Or should I leave them off and apply heat shrink them? I was thinking that the install would look cleaner if I can reattach them to to voltage regulator.
