Stebel Horn Wiring Question

[nhchris]

I have an aftermarket Stebel  LOUD horn I'd like to install on my FJ.   But...

The Yami OEM horn has two connection wires and the Stebel horn has only one. I assume Stebel horn makes ground connection through the mount.

Anybody have advice on how to wire in the Stebel using only one connection wire from the FJ?  Thanks!

You are correct, ground through the mount.  You can add a short piece of wire, with the proper connector, and connect the OEM ground to a mounting point on the horn. 

Also, check amps needed for new horn.  Many aftermarket horns draw much more than stock, so stock fuse may blow upon use.

I use the factory wiring to trigger a relay, with separate power/fuse to the replacement horn.
