Electric Brake Control 2005 Silverado
I am trying to find where the wires are to attach electric trailer brakes on my 2005 Silverado 1500 4WD. Am I blind?! Does anyone know where to locate the wires?

They're underneath your truck towards the back, somewhere. Chances are they're hidden so they won't fall and possibly drag. You can check on top of your spare tire, and other locations under your truck.
I'm assuming it's equipped with a towing package, obviously.

I see the all the pre-wired harnesses back there. Shouldn't there be four wires (red, light blue, dark blue & black) under the dash somewhere for the brake controller to attach to? I am using a voyager xp controller. The truck does have a towing package, I have used it for other trailers without brakes.

Thanks. I was looking for where it would be stored. I bought the truck last year and I swear the dealer told me it was ready for trailer brakes but I can't seem to find the connector.

under the dash where your left foot goes, just above it you should see where your controller plugs into. also you need to install a 50 amp. fuse into your fuse panel in the engine compartment. everything else is wired. just add your 7 pin plug in the back..

Thanks everyone. I went to the dealership where I bought the truck last year, a different salesman helped me out and gave me a Z73 brake adapter. Haven't installed the brake controller yet but...
The DRK BLUE on the brake controller says 'Trailer Brakes' but on the new harness from the dealership it reads ' Trailer brake controller switched output device'.
Hope this is the same thing and I have the right adaptor. Any thoughts?

I had a 2000 and the Tekonsha that came with the truck was simply plugged in above my left foot like desrtrat said.. I can't imagine they would have changed anything like in those years.. The panel was about 6"x6" and if I remember correctly had room for about 4 or 5 things to plug into it.. One of'em was the brake controller..
