Im not sure how to install it properly. "Properly" meaning that everything is working. I'm familiar on how to take the wheel off, align, etc...But I'm not sure about the horn. I was thinking of making a feeler gauge to meet with the back of the brass momo hub. Which wire is the horn lead in an EK? Blah...this is goin to kill me. Someone help....please.

P.S.
I did try searching.
