Review: Easy to hook up and install. Works great when going from single horn to dual horns - Helped my Harley go from a single horn to dual Motohorns! NOW, those crazy cage drivers can hear my horns when they don't look when changing lanes.
Review: good quality harness - I also ordered a pair of their high and low tone horns with this harness. Installation will vary depending on the vehicle you own. Mine was for a 68 Pontiac GTO. I listened to the horns from their ad and liked the sound. They did not disappoint. I wanted that big GM car sound of the 60's. Be prepared to have some additional same gauge wiring and connecters on hand as I had to lengthen the harness for my application. I purchased a horn button from a local auto parts store which came with it's own wiring. Take your time, the instruction diagram is easy to follow and is in color. I'm a happy camper!

### ⭐⭐⭐⭐ Decent
*by B***A on November 18, 2025*

Decent overall but the wires for the horns should be longer considering in most cars the dual horns are mounted further apart.
