Theres a red wire from the ammeter gauge to an accessory circuit breaker. Where is it and what does it look like? I have the '66 service wiring diagram but I don't know where the breaker is. According to this diagram there are 2 red wires from the ammeter gauge , one to the engine bay, one to the accessory circiut breaker. That wire is not there, and because it's not there I can't find the the breaker. Thanks.
