I just installed a momo hub and s. wheel and know the horn don't work?? has any one else had this problem/ If so how can I fix it?
thanx for any help you guys can give.

 

Your green should go to the chassis of the momo hub and the black should go to the button. Or vice versa.

The chassis is the ground and the button is the open.

Try reversing the wires before you tighten up the wheel.

 

Thanx but I already fixed it. It was that the plastic that holds in the copper contact was raise up higher than the contact so I sanded down the plastic and voila' it honks again.
but thanx for the reply.
