    Anyone find an easy access through the fire wall on the 2015 Silverado 2500 HD? I am having a real tough time finding a spot to run the control cable into the cab.

    Right above the gas pedal as high as you can get the drill in. It's easier to drill a hole there then try and use an existing hole. Kind of inline with centre console. It's hard to explain unless your under there. Lol

    There's already a rubber boot there. From inside the cab it's in the top left corner.

    This is a picture I found online from an 09, but it's basically the same on my 15 GMC.

    I was looking at that boot. There is so much sound insulation in the cab, I couldn't see where it was on the inside. I'll poke around there in the day light.

    There's a connector junction box more or less behind the parking brake pedal. The boot is behind there, it's not really visible, you need to feel for it. I used a fiberglass fish stick to poke though. It's a little easier if you remove the nuts holding that junction box in place so you can move it some. I did not disconnect it.
    I also ran a string through tied off inside the cab and engine bay to make it easier to run additional lines as needed.

    If its the same as the 1500 that boot is double sided .Pain in the butt to get through both sides but doable.
