Gnome Posted July 5, 2020 Report Share Posted July 5, 2020 Does anyone have a good diagram and part number that is readily available for doing a 12v conversion and rewiring the horn relay. i bought a new on but it has 3 terminals on it as apposed to the 5 or so on the 6v. oh and It is a 1949 Plymouth deluxe.

Plymouthy Adams Posted July 6, 2020 Report Share Posted July 6, 2020 the standard 12 volt Bosch is about the most readily available relay and associated pigtail you can get on the market today for a quick clean install....as for the horn wiring you will want supply to be coming in on 30, fused if you like and you can jumper this hot wire to the relay coil terminal 85 as B+ for the coil circuit. You will connect the horn to the output of the relay on terminal 87 and connect the wire running out the steering column from the horn button on terminal 86. 1 1 Quote Link to comment Share on other sites More sharing options...
