Ok since its cold out, I tend to find a lot of useless things to do with my time. Today I decided to try and install a air horn haha... Anyway the directions have it setup where you run the original factory horn wires to a new relay which a ground, the main 12v and a wire running to a switch, then to the new air horn is connected. Well I dont want the Airhorn to be used as my regular horn. So I bought a push button switch. So the spot on the relay where the existing horn was to go i left blank. Anyway when I Hooked it up, did not work. When I touched the empty spot (where existing horn should be) and the 12v slot with a piece of wire.. it went on... but on constantly regardless of the switch. Can someone help me with how to hook up this compressor, so that it will be activated by a switch? Thanks!
