Ask Your Own Mercedes Question

Ask Your Own Mercedes Question

did you order the correct horn?

Ask Your Own Mercedes Question

Customer reply replied 9 months ago
I can get it to work if I hook up the power/hot wire and touch the ground to something, but not if you push the horn only when I touch the hot and neg wires.

you need to find the hot from the plug with the horn button pressed

Ask Your Own Mercedes Question

then just ground the other wire

Ask Your Own Mercedes Question

though i would recommend getting the correct 3 wire horn

Customer reply replied 9 months ago
I will have to wait till I can actually be at the horn, to work this out. I did look for the three wire harness, I can not find it.
