Rebel,
Probably the black wire is negative.
For wiring a horn it usually doesn't matter which wire goes to which post.

Got it working. Black was negative. The relay that came with the horn was bad, had to borrow a meter to discover that. Took 4 or 5 hours in total before we checked that **** relay. Works fine now. Very loud. I can recommend this horn.

Denali Soundbomb in case I didn't mention it.

Was thinking of adding that to my wife's bike. Did it require you to fabricate any brackets for it and could you maybe post up some pictures of it mounted. Thanks
