The original steering wheel on my 1995 Mighty Max had been replaced with an aftermarket steering wheel and the horn was left unhooked. After removing the steering wheel, there was only one wire visible, a black ground wire. What do I need to do to get the horn working again?

Hopefully the horn button will have 2 tabs . One for the positive connection the other you just have to get a piece of wire and add a spade type fitting and a flat type fitting to sandwich under where the hub is allen keyed to act as an earth ;) . I will take a pic in a coupla days , believe it or not i did this not 6 hours ago. If you hold that wire that is on its own against the hub the horn should work ,and if that is the case - what i just said is a really simple fix ....Cheers ..

Thanks for the reply. I'm looking forward to the pics, as they say, a picture says a thousand words. Does your horn have two wires coming from it? By the way, the horn button on the after market steering wheel does have two tabs on the back of it. Also, I can't locate the hot wire. I don't even know what color it's supposed to be. Thanks again...
