Ok, I used some copper wire (like 12 gauge) to make a brush out of. It works great. I took the Z out and tested the horn several times, it worked every single time.

Thanks again guys for all of your help!

Matt-

Keep an eye on it, so that the wire doesn't catch against the steering wheel surface and then gets bent and makes contact with the steering column....that would make the horn sound continuously.

Glad it helped!
