I bought a 99 herritage softail classic it had no turn signals on it. It has the wires for them under the seat. Just wires no plugs. The wires are black brown violet and blue. So i know those are for the turn signals. I took off the gas tank to see if there was a plug for the front turn signals and there is a plug up there for them. So i touched the wires from my rear turn signals to the open wires i found under the seat and all it did was turn the light on they just bulbs not leds. And when i press the signal button it does nothing. So I guess im askin what all do i need like maybe a relay and a tsm or what? Help plz been fighting it for a week now.
