I just tried to replace my stock horn with an air horn. I couldn't get the new horn in so when I was putting the body work back together I found a plug with three wires in it. I think it's a female plug end. I Can't See if there is a male plug that goes to it or if it might just be a plug to some option. All the lights seem to work ok so I'm stumped. It was in the same bundle of wires as the horn wires if that's any help? I don't want to put everything back together until I can account for those three wires in that female plug. PLEASE?
