Thrash,
On my 1996 Sidekick Sport, there was a push button type switch that was pushed in when the brake was lifted up.
I was going to splice in another switch and mount it next to the gear shift so I could cut the connection when needed (such as when I hunt and don't want to drive up to the clear cut with my lights on).
I sold the vehicle before doing so, but plan on doing the switch install in my new-to-me 2002 Vitara. It seems to operate in exactly the same manner.
