A auto electrician mate mounted a switch in the dash ah la loaded's (except mine is a toggle with a label for on/off), via a relay from the back of the ACC socket on the dash, this also runs my GPS/Pocket PC, and is fused, we shorted it to double check.
We had already used the power from the horn to upgrade the lights to run both hi/lo when high is on, that would be another source you could use.
