While we do have brake controller options for your 2017 Tiffin Allegro Red Motorhome, on a 2016 Freightliner XCM chassis, we aren't aware of any plug and play connectors on the chassis itself. The only options we have require splicing but if you found a plug for a brake controller you can easily cut off the connector and splice a brake controller to that.

For your application I recommend the Redarc Tow-Pro Elite # RED44FR because it installs out of the way (you only need access to the control knob) and it can switch between proportional braking and time-delayed braking, giving you the most control over how and when your trailer brakes are applied (see attached video).

You will need to connect the following wires from the Redarc pigtail to the following functions:

Blue - 7-Way Output to Trailer
Black - 12V Power
White - Ground
Red - COLD Side of Stop Light Switch (only gets hot when brake pedal is pressed)

You can use a circuit tester like part # PTW2992 to determine these various functions.
