Question:

The red wire on my brake controller dose not work on the plug under the dash. How can I get it to work?

What is the year, make, and model of the vehicle? The red brake controller wire should only be getting power when you step on the brake pedal. If you are not getting any power on that wire with the brake pedal depressed then you may have it attached to the wrong brake switch wire (if it is hardwired into the vehicle), the red wire is in the wrong location in the plug (if it is a plug in application) or you have a blown stop light or CHMSL fuse.

I would need to know the year, make, and model of the vehicle to determine which is the likely problem. If you suspect it is a fuse use the owners manual to determine the fuse locations.
