My 68 SS 396 clone wiring harness on the car has a combo horn relay/buzzer that has a factory wire pink w/blk tracers that plugs into the relay on back side. That wire does not show on any factory schematic for that year-what does it do? It does show on full size chevy schematic?? Also there are 2 male connectors available with nothing attached. What are they for? Schematic shows voltage regulator but this car does not have it so I assume it has been converted to an alt w/ internal regulator where do I find that schematic? Thanks Mike
