I see I made a mistake by not telling that the horns are not on a car or truck I pick them at a swap meet and would like to test them before mounting them. The relay has 3 terminals one on each end of the relay and one in the middle. The wire from each horn is hooked up to one of the end terminals the other terminals have no wires. I am not sure which terminal gets the 6 volts and the other would be a ground.
