Gmt-800

[07AFSilverado]

I have a 2007 Classic Silverado and am trying to locate the wiring plug harness location up under the driver's side dash. I have searched the threads, but they all seem to be in reference to GMT-900s. Are the 07 Classic's still plug and play? Where is the location at under the dash? Do I need to plug it in the fusebox area or are there wires just taped underneath somewhere? Thanks for your insight.

There is a box above and to the left of the brake pedal that you'll plug the harness into. You can either get a harness with the truck side plug and bare wires on the other end to connect to the brake controller wires or I think you might be able to get plug and play harnesses for some brake controllers.
