Hey All!
I have a 2015 P4X with factory installed tow package. About a year ago, I installed a RedArc TowPro Liberty brake controller to help when towing my camper. Installation was 10 minutes and has worked great.... until now.
For some reason, the brake controller has stopped responding when I press the brakes. Strangely, all the lights work on the camper when connected to the 7 pin. I have checked some of the fuses under the hood, and all good, even replaced them to be sure. The only one I can't figure out is the fusable link that may be part of the tow package.
Got a camping trip in a few weeks and need to get this fixed!!
Any ideas??

Car brakes but you have to push hard?
It was brake assist in my case, crack and loss of vacuum.

z1offroad has it and dealers. OEM is a better fit I was told.
Goes between master cylinder and brake pedal

Brake Booster out at 203k, anyone else?

4 days ago my brake pedal had issues… sometimes. Needing a harder push, still not normal then, back to normal, then not. 600 miles later, a bit of hills and it’s official, it’s not going away, needs a new Brake Booster. Scary moments a few times, then feels normal and back to not. has anyone...

Never used a RedArc.

I've had two different Curt inertial controllers fail on me.

Using a Tekonisha (?) now.

Point being, brake controllers do fail. Throw a known-good unit in there?

UPDATE! This stupid fusible link was bad. Found a OEM on Amazon for 10 bucks, and switched it out. It's located in the "big" fuse box on the firewall.

Hope this saves others the same misery!
