I have an aftermarket electric brake controller.

I have an aftermarket electric brake controller connected to the wiring harness in my 2008 silverado 4x4 5.3L 1LT (new body style). When I press the brakes, the electric brake controller activates but after I release the brakes, the electric brake controller does not disengage. I can get the electric brake controller to disengage by just lightly tapping the brake pedal. I've already swapped out the electric brake controller and I'm confident I have it wired correctly. The original electric brake controller was wired into the vehicle for 4 years now and working just fine up until 6 months ago. Is it the brake switch? Any suggestions on how to diagnose it?

Thanks,
Kevin

I would be checking that the brake light switch is coming all the way off and there is no voltage leaking when it is off.
