Hi Mike!

The etrailer Trailer Brake Controller Installation Kit - 7-Way RV and 4-Way Flat - Detachable Harness # e556GR will absolutely allow you to install the Redarc Tow-Pro Link Bluetooth Brake Controller - Off-Road Mode - 4 Axles - Proportional # RED57AR!

The # e556GR includes the TowSmart ProClass Trailer Connector - 4-Way to 7-Way and 4-Way Flat - Vehicle End # TS59RR which has the USCAR connection on the back that will allow the Redarc controller to plug right in (see included image). Then you just have to mount the box up and out of the way and you are good to go!

What vehicle are you wanting to install this on? And what will you be towing?
