Your Avalanche should be prewired for a brake controller. Check the fuse panel in the engine compartment. Remove the outer and the inner fuse box cover, and on the inboard side of the fuse box, you'll see two threaded studs. The stud closest to the rear of the vehicle powers the brake controller, there should be a 30A fuse installed next to it. The stud closest to the front of the vehicle powers the 12V feed to the trailer connector. There should be a 40A fuse installed next to it. If the fuses are missing, you'll need to install them.

I'll link to an article that explains how to install a brake controller on a 1999-206 full size GM truck or SUV. I've also linked to an article showing a typical brake controller install on a 1st generation Avalanche like yours.

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
