Ok guys I need a little help. I have a horn that plays a horse sound. I want to activate the horn using an led remote unit. The unit will be separate from my led lights. It has a 2amp fuse inline and I assume that is the max current draw. The horn unit is triggered by one 12volt pulse. In essence I want to wire the horn controller through a relay and trigger that relay with the remote. The relay must not permanently latch the circuit but only provide a momentary trigger pulse then shuts off and resets. I'm racking my brain. I know someone on here can help.
