    Default Brake Controller Power

    I'm trying to hook up a Tekonsha P 2 brake controller in my 2009 2500 HD. Would anyone know why there isn't any power on the underdash factory trailer leads? I installed the 40 amp fuse but I read in the manual the wires aren't connected? Thanks.

    That's a first, that I've heard of. I've never come across one where if the wires were there, they weren't at least powered... Have you checked your wiring diagram to make sure you're hooking up the right colors (or are you using a plug connector?)

    Skippy.

    Direct wire. I guess with '07 and newer you have to do a hard wire connect if you don't have the factory integrated brake controller.The harness has a red/black #12 awg wire marked battery + but no power on it .Fuses all good .Don't have a wiring diagram so don't know where to look.I'm going to by pass and feed from elsewhere for now just to get me through the weekend.

    I haven't looked for it, but it is somewhere near the front fuse box and connects to a screw post under the cover. There should be two wires, one is for the trailer battery feed, also two screw posts, sized to accept the different sized connectors on the wires.

    I can confirm this to be the case on NBS trucks, as I recently went through it.

    Just a j type fuse and with the help of surreal's link I was able to locate the hidden wires .Bingo! Power to the connection. Now I can head out camping for the long weekend knowing I've got a properly connected brake contoller. Thank you to all.
