That would be a good reason if the horn button can't carry the load. i am just use to buttons being able to easily handle that load.

I'm sure that wolo put that in there just as a safety measure to make sure it worked for all situations.

As posted earlier, be sure the ground cable back to the bat is as large as the sopply or you may find your mp player droping out due to the voltage drop when the ground sort of backs up the electric. Is that clear??
