This is the way that I see it from the instructions. If the horn button works as a grounding switch it won't work.  It must send power to the relay to activate it.


Horn does go to 87 and if one side of button is grounded connect button to either 85 or 86 with a low rated fused supply to the other.
Large rated fused supply to 30

I see what you guys are saying. If I junction a fused power wire and the "86 wire" from the button and then lead into 86 on the relay, the button will now be grounded and have power. The problem was I didn't have power at the button. Correct?

The circuit diagram for your bike will tell hiw to actuate the relay. Some horn buttons ground the horn, 12V constantly connected.

The stock horn must have 2 wires. If you connect both these to relay coil it must react when horn button is closed. Then connect the power to 30, going out to horn the other terminal. Horn grounded as it should.

Yes, as I mentioned I had it hooked up that way and it didn't work. 30 fused power in, 85 to ground junction, 86 to horn button, 87 to horn. The horn has + power and 87 going to it. The button has a ground and 86.

My question is should I junction a fused + wire with 86 so the horn button has power sent to it as well as ground? See above.

I'm sorry to be rude but from your questions you simply do not understand the principles of electrics, i would therefore advise you to get somebody who does to do the job before you totally wreck the loom and/or cause a fire.

I got it to work. I was correct one of the wires at the button need power. The horn is grounded instead, unlike the stock diagram. I think there was just a little miscommunication. Thank you for your help!
