I am trying to implement a dual horn setup for my bike. The stock came with a single horn. I have with me a 3-pin relay(H-B-S) with me. I am connecting the positive from the battery to the B terminal, Horns connected to the H terminal (horns are grounded on the other end). By what the relay box specifies i need to add the S terminal from the relay to ground via a switch (not the stock switch provided on the bike). So when the switch is turned on the horn sounds. This works as intended, but I want to use stock horn button to activate the horns. What should i do for that.
PS: I tried connecting the stock switch in place for the switch in the diagram (by connecting a terminal to the S and the other to the ground), but it does not work. I dont know what polarity is being supplied by the stock switch. I tried connecting the switch both ways to the S terminal, these are the outcomes for that scenario
- The horns starts sounding continuously (with out the switch being activated, bike still in ignition off position) untill i pull out the power wire from battery
- No response even when activating the switch
Attaching the wiring diagram of the Relay.
Can this be done on a 3 pin relay? If not I Should go forth and get myself a 4 point relay as I know this can be done with a 4 point relay. Thankss
