Dimmer switch for PacBrake?
« on: September 19, 2026, 06:39:51 PM »
I've searched the forum and didn't find anything. I want to mount an old-style foot dimmer switch on the floor so I can activate the PacBrake with either the factory rocker on the side console and/or a floor-mounted dimmer switch. Can I add a floor on/off dimmer switch by wiring it in parallel to the factory rocker switch?
I know PacBrake makes a floor-mounted switch, but it's a momentary switch. I don't want to keep my foot on the switch.

I think it would be easier to press the foot switch instead of hunting for the console-mounted rocker switch. My coach is old enough that it doesn't have the switches in the center of the steering wheel.  Thanks!

I can't see any reason why you can't use an old style foot dimmer switch in place of the rocker switch up on me console.
Just be aware that that switch controls the exhaust for pack brake through the engine ECM and transmission TCM.
the ECM commands the pack brakes solenoid operation using criteria to control down shifts and maintain an optimal RPM for exhaust breaking.
ECM also controls the RPM and road speed at which the pack break drops out to avoid stalling the engine it stops.
