I know on my family's old 97 Chevy tahoe, the DRLs would come on whenever the parking brake was applied, no other way to shut them off...so the trick I learned is to apply the parking brake pedal just enough to hit that switch. Usually only one or two clicks away from the full release position...it shuts the lights off, and isn't applied far enough at all to actually have dragging brakes. The indicator light will show up, but if you can live with that, go for it. I know on my 90 Tracker I can pull up on the parking brake lever one click and the "BRAKE" light will show up, but the brakes aren't actually applied, the microswitch is "fooling" the electrical system into thinking it is.
If that works for you, it's more temporary and doesn't require you to delve into any wiring.
