The best brake controller for your 2019 GMC Acadia with a 7-way is the Redarc Tow Pro Elite part # RED44FR that you referenced. This is a proportional controller that senses how hard you are applying the vehicle brakes and applies a relative amount of braking pressure to the trailer brakes. And also this only requires mount a small knob on the dash instead of a box that can sometimes get in the way and be an eyesore.

Next, for a wiring kit to install the brake controller to the 7-way you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506. This will provide the power source and ground for the wiring for the brake controller. You will need to test the wires from the brake pedal switch of your vehicle to find a circuit that has voltage when the brakes are applied and none when not applied. This will be the circuit you will run the red wire to.

Finally you will need to run a length of 10 gauge wire (part # 10-1-1) from the brake output circuit of the controller to the brake output circuit of the 7-way (blue wire). The # 10-1-1 is sold by the foot so you will need to order a quantity of the amount of feet you will need.
