Picked up a Momo wheel and correct hub for a 86 944 and for some reason the horn does not work when I tap the button. Now when I take the wire and touch it to somthing else on the wheel the horn works. So is it the metal on the button or what? All I know is from the stock wheel to this wheel it is one wire so I did not think this would be that big of a deal.

 

the horn button is not grounded . you might need to make up a small jumpper wire to go from the button to the wheel to get a good ground .
