    I'm new to this site, and think its great. Lots of info to learn from. I was wondering where the wires are for the roof light on a 2004 Chevy 2500HD with plow prep pkg. Thanks in advance.

    Should be above the headliner, center of door opening. Runs up from the right 'B' post.

    FA.........HOLD UP !!!!
    .....The wires run from bottom to top
    in the LEFT Rear B pillar. NOT the Right !

    If you have a reg cab the easiest way to find is pull the
    plastic piece in the LEFT corner of the cab next to rear
    window

    You are looking for a Brown+ and a black wire-

    I have a 2003 with the exstended cab and I was able to find mine at the door latch stricker up by the head liner on the driver side.If you pull the liner down slightly at that point and shine a lite in there you see a wire rolled up in about a 5" diameter loop.Thats the one its taped to the roof I grabbed mine with a coat hanger and pulled it write over no problem

    is it hard to install the light kit?
    does the headliner come off easy and go back in easy?

    i bought the lights for the roof.
    I was wondering if the headliner came out easy since i would have to drill holes for the light wires to come in the cab.

    I decided on a roof mounted visor with running lights built in lund has an excellent product for the truck

    We used the wires from the roof light to power strobes..works well...makes a nice easy stock installation.

    IH..............On my ex-cab thats how I pulled my wires out!
    To take the plastic piece off the B pillar you have to remove
    the rear seat and seat belt.............PIA !!!!!!

    Stanza..........Gotta be VERY careful with that headliner !
    It is held up with CHEAP plastic clips. If you break them
    you are in for a hassle !

    I just got a male/female plug and mated them to my strobe
    and factory wires. Plug/unplug and remove as necessary!

    I just hide the truck side plug in the headliner when not in use.
    I just run it out thru the door jamb when needed..........geo

    WARNING...............

    Before you do anything......TEST those wires for power first!

    I have read posts at "the other site" that GM FORGOT to
    put the power wire to the dash switch on some 03-04s.

    So a few folks have had to make a trip to the dealer to
    fix!

    According to the GM upfitter site I posted you will be looking
    for brown + and black- wires.

    Print it out and keep......Lotsa good info....................geo

    NO its not you Gadget !........Its GM !

    The pic is screwed up on the GM upfitter site ! I think the artist was buzzed the day he drew it !

    At first we thought the wires were in the ex-cab door !
    NAH...Couldn't be !

    Had a few of us scratching our heads when the new body
    style came out in 99 searching for those wires !

    Dealers were clueless !!!!!!!!!!!!!!............geo

    I want to thank everyone for your help. Sonjaab, I like the way you wired up your light. If I can find those wires I will do the same. Thanks Again

    STANZA & FAV..............Just a thought.........

    Instead of yanking the headliner you could take down
    your overhead console. Its only held up with one ?
    screw in the front of it and tabs in the rear.........

    Let it down and it will be far enough back to fish
    out the factory aux. light wires....... then drill
    a hole from the inside out and hook up the wires.........

    If you drill from the top down...make sure you vaccuum up all
    the metal chips.. If they get wet they rust and stain the
    headliner !

    Heres another....You could lead the wires out the back of the
    roof....Just take off the 3rd eye brake light and lead them
    out there............

    Almost forgot about those !!!!!!!!!...........geo

    Nice file, any chance you would have something about the OBS trucks? My 98 has the prep package but don't know what all it gets.

    BOWTIE..............Sorry I never could find any info on
    88 and up OBS GMs plow prep. except what the dealer
    brochure said.

    I assume the OBS trucks had the same stuff as 99 and up.

    NEVER did find the aux. light wires on my 90-94-97 GM
    trucks. Didn't wanna tear up the headliners looking so
    I just used a mag. mount light pluged into the cig. lighter.

    Amber flashing light required by NYS law while plowing !

    Dealers were clueless where the wires were !

    Again MANY thanks to the person who posted that GM link
    here a few years back when we got our NBS trucks!....................geo

    I know this might sound like a stupid question, but I just want to make sure I'm in the right area for the wires. I don't want to be tearing down the whole headliner looking for them. So by the looks of page 6 on the Gm upfitter site, I should look where the front door and back door meet on the drivers side on a ext. cab. Thanks again......Favatts

    Sorry but what year is your truck?

    Mine is an 03 silverado with the plow package and I have a button on my dash board for this wire. Do you have a button to turn on your light?

    IF YES

    I found mine write where you described it I just pulled off that piece of molding and fished it out with a coat hanger
