Expert Reply:

The wiring to install a trailer brake controller is located under the dash of your 2010 Chevy Avalanche. There will be 4 or 5 wires held together with a white tag that lists the functions of the wires. The bundle should be under the dash to the left of the steering column.

If using Curt brake controller # C74VV you will also need wiring harness # C51515. The connections should be as follows:

Brake controller white to truck white for ground
Brake controller black to truck red/black for 12 volt power
Brake controller red to truck light blue/white for input from brake switch
Brake controller blue to truck dark blue for output to the trailer brakes

If there is an orange wire it is not used. I have included a link to an FAQ article that will also help. There may be some additional connections you will need to make under the hood to make it all fully functional. I have also included a link to a video showing a brake controller installation on a 2013 Avalanche which will be nearly identical on your truck.
