If you power one side with +12v and carry the other side to ground, they will work. I have them on my 4Runner.

I did ultimately end up running my own power with a relay as it was louder.

Ok thanks for all the replies.

Why would I need to clip the wires? Both horns have female connectors that fit onto the Hella horns perfectly. The only weird thing is that the driver side horn has two wires and the passenger side has only 1. I suspect the two oem horns are wired in-line for power and using the bracket as ground?

Separately, a friend who's an ex-Ford mechanic mentioned I may not be grounded because of paint between the bold ground wire I'm using.

Aaarrgghh.
