You will need a dedicated brake light circuit (a circuit that only carries the brake light signal) to attach to the brake controller red wire. The CHMSL circuit (center high mount stop light) does fit this description and you can use it.

Finding the correct stop light wire on a 2013 Equinox is different than on other vehicles. To get it under the dash you need to access the BCM (body control module). It is located under the dash above where your left knee would be. The module will have several different wire connectors that plug into it.

Look for the black connector (all the connectors are different colors) that has 26 different slots for wires to insert into. In wire position # 11, there will be a white wire that carries the brake stoplight signal. Use the quick connector to tap the red brake controller wire into this circuit, and you will be good to go. Be sure to use a circuit tester like part # PTW2993 to confirm that the white wire only shows voltage when the brake pedal is pressed.

I included a picture that states up to 2012 but should also be for the 2013.
