Thank you guys very much for the advice.

 

This is what I used

 

I bought a relay kit. I have no idea how to connect it. I know one red wire connects to the positive on the battery. But the relays show connection to the compressor of the horn. My Minibeast is not an air horn. It has no separate compressor.

So where in the name of CANbus do I run the wires. I have the 2015 Ultra service manual and they don't show where the horn wires are located or if they do, I can't find it.

Thanks again.

 

Custom dynamics has an install video.

 

Check your main horn assembly. My newest one has the relay attached to the overall assembly which mounts on the old horn mount. Without this relay, you would be blowing fuses as the horn draws quite a bit of current.

 

I watched the video. "Follow the wires of the stock horn." I followed what I could, but it felt like they went under and forward. Suffice to say, the route was different from on the video.

I like Onramps thought - that there is a relay attached to the overall assembly. Although I don't see that on mine, it might be an easier install. To the dealer I'll go tomorrow I guess.
