Bob, just noticed this Visitor Message. Never used this before, only Private Messages, so I apologize if I missed this and didn't respond.

The wiring schematic can be found in the Tempest Shop Manual, it was same for all V8 including GTO.

There was a revised schematic issued in a '64 Service Craftsman News, I think Issue #2 or #3. I think there was just a minor change to a couple of the wire colors.

Hope that helps.
