Wonder if anyone can help. I'm looking to connect a Zumo to a Tiger Rally Pro 900. With my previous Tiger 800 I used the live in the horn and just connected the earth to a nearby bolt. I've tried the same with the Rally Pro and it's not worked but I think the piece of wire I wired in with the Zumo wiring is providing power since the horn still works. Anyone know if there's any reason it shouldn't work on this bike?
