    my truck is a 01 with the trailer package....

    I know it has some wires down by where your leg is when sitting in the driver seat. however, again, I forgot!!! anyway, what color are they, and how hard is it to hook up my brake controller that has 4 wires (battery,stop light, brakes, and ground) so my truck?

    thanks guys.

    btw. someone told me like 3 times how to do it, however im a dumba$$ and cant remember for beans

    or do i just get a new harness that has the adapter on the other end for the part under the dash? or do i have to manually splice some wires?

    Most of the manufacturers sell a standard plug for pre-wired trucks. I got the Ford adapter from U-haul and I think both Draw-Tite and Reese had them in their catalog.

    You just use crimp connectors to attach the new plug to your brake controller, and then plug it into the pre-wired jack under the dash. On my Ford I also had to install two additional fuses and a couple of plug-in relays to make everything operate on the 7-wire plug at the bumper.

    Does my 03 2500HD have the plug under the dash? Where would I find it?

    Look to the left of the brake pedal on the fire wall, you will see a black plastic cover with a tall nut in the center of it, remove the cover and your plug for the brake controller will be the second slot from the left on the top row of open slots.

    MARK..........Hows that new ride? I know where ya got it from !
    I thought I had seen pics of it before.....................

    Anyhoo..............To get power to the rear plug for the brakes.....

    Make sure the fuse lug in the underhood fuse center is in place.
    GM usually has a plastic dummy lug in place instead of a fuse.
    You must get one and insert it............

    Also GM in its wisdom didn't hook up the power wire UNDER the
    fuse center in some year trucks. Same with the aux. lighs switch too !

    Also remember Gm changed the pin arrangement in 02? or so so a
    earlier/later plug will not work untill you swap 2 wires.........

    CONFUSED >??????? Take a trip over to http://www.gm-trucks.com
    or http://www.fullsize chevy.com
    A few threads concerning this problem and how the guys got fixed
    up !!!!!!!!!!
    Also check your owners manual and check those threads.........geo :drinkup:

    lol ya sonjabb I love it. Its sooo sweet.

    I did get it hooked up, I was supprised how easy it was to do, I thought it would be harder than just plugging it in.

    I cant even tell im towing my new trailer, well I can sense I cant see around it, lol, other then that it tows like an ox.
