FARBINAir Horn Relay Wiring Harness Kit 12V 80 AMP for Car Truck Motorcycle (Relay 4 pin Single Horn Wiring Harness, 12V)

Works like a charm, easy to install. horn power and ground leads are very short, so the relay must be mounted within a few inches of the horn. For me that means above the radiator where it will be exposed to rain and dust. Time will tell how well it holds up, but for now it's certainly worth the $10 I paid for it.

Used to install train horn made it super easy

the red and the yellow go to battery. the rest was easy.. blue wire is hot that send power to a horn relay. .. this went on a c3 cooler for wireless lights and horn...works great after i burnt up 6 rc controler boards to figure it all out works like a charm now..

I bought these to replace my 2000 Honda Civic CX horn buttons on the steering wheel. The OEM part from Honda varied from $100 to $200 for a little plastic box with some metal contacts, a spring and button cover. Used one button to activate my original "beep beep" wimpy Honda horn. The other to blast a freight train horn I bought here. All worked great except after 3 days one of the buttons stopped working. (I had only used it a few time for testing.) Cut it off and brought it inside to find one of the wires inside had come loose at the soldering point. VERY inadequate amount of solder used. I figured better replace the one that hadn't broken yet too. Button front is just a very thin plastic sticker, peeling it off reveals the button switch underneath. But then I found it wasn't necessary to peel off the button front. Using an extremely thin jewler's screwdriver, I was able to wedge it in at the seam and pop off the back from the front case. Resoldering thicker wire required snipping the back cap and housing to make a larger whole for the wires. Works great now and saved almost $200.

I installed this when my original horn button broke and it was going to cost me over one hundred dollars to replace the factory horn button. This is a VERY EASY INSTALL!

The horn on my motorcycle wasn't working and I needed to pass inspection. The fuses were OK, and I replaced the relay. It still wouldn't work. So I decided to just wire in a whole new horn circuit. This one comes with the button, relay and all the wiring you need. In 15 minutes, I had a working horn that will pass inspection.

It was easy to follow the instructions with graphic. High quality product.

Used for my horns didn't last 3 days
