Horn relay wiring question

[BHTENERE]

I have installed a pair of Fiamm horns on my bike and will be installing a relay to power them. I was wondering if anyone knows of a wire tap point for the existing horn button wiring that is in the wiring harness by the battery area, that I can use to trigger the relay? Or, do I have to run some wires up to the existing horn location to use the two wires there?

We have a Horn? I never use it. Must be an east coast thing!
