Re: wiring a aftermarket horn with relay
40 cpe i totally understand what you’re saying the relay has 3 terminal on it. Horn. Bat. Switch . so if i ground the switch terminal then the relay will be energize full time the truck has one original horn that works there’s power on both terminals one is bright and one dim when i activate the horn button the dim one goes out so i assume that would be the ground side those horns are wired hot all time just saying
