I always stick with Tekonsha brake controllers, specifically I love the P3. They make a factory wiring adapter so you just plug one into the controller and the other into the factory hookup. Couldn't be easier.

Tekonsha - Trailer Brake Control Harness
The nice thing about one like the P3, it will do electric or hydraulic over electric, nice to have the flexibility to not limit yourself in the future.
I also have a 2013 SL. Love my truck.
