Danchuck 1957 Horn Relay Wiring Help - TriFive, 1955 Jan 22, 2010If anyone can look at the wiring on their 57 chevy and tell me what color goes to what terminal I would greatly apreciate it. Danchuck said they would get the horn relay and hook it to a new wiring harness and call me with the color but they are short handed and not sure when they can look at it. Help!!!
