Based on my research, it looks like your 2012 Monaco Knight Motorhome is built on the custom-built Roadmaster Chassis. We do not currently have a plug-in wiring adapter available for your RV, however there should be a built-in harness next to the air brake pedal. You will just need to connect the wires from the brake controller pigtail to this harness.

I highly recommend the Tekonsha Prodigy P2 Trailer Brake Controller # 90885. This is a great proportional controller that will activate your trailer's brakes at the same time and with the same intensity that you apply to them in your RV. It has an easy-to-read LED display with continuous diagnostics that will alert you to any potential issues. The controller will include the pigtail harness needed for installation.

The red wire from the controller goes to the brake light circuit, the white goes to ground, the black to 12 volt power and the blue wire goes to the brake output. I recommend using the Redline Quick Splice Wire Connector # SWC501915-1 to make connecting the wires quick and easy.
