Question:
I have a 2022 Newmar Super Star RV built on a Freightliner M2 chassis with air brakes. I need to install an electric trailer brake controller and want it to be able to plug in to factory wiring harness. What products would you recommend?

Hey John, we unfortunately don't have any brake controllers that have an OEM plug that will work with your harness on your Freightliner. I did some research and was able to find some one-off harnesses that allegedly work with your RV, but the majority of owner's had to cut off the plug and splice in.
Going down that road, I'd suggest going with the Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness # RED52VR which comes with a universal harness so you can splice in.
This brake controller will work with up to 4 brake assemblies and only leaves a small control knob exposed when completely installed.
If there is anything else I can do for you, please feel free to drop a comment and let me know!
