Hey guys, new here and I could really use some help. Ive got an 05 2500HD 6.0, 4WD, auto and am in need of a complete wiring diagram. Ive been trying to google it for about 2 hrs with to no avail. Ive ordered the haynes book as no one around had it in stock, but was hoping someone here could point me towards somewhere thats got them online or has some i could get until the book comes in. Got some crazy electrical stuff going on I need to get sorted. Thanks in advance

Hey Aaron, I have a 2004 model and would like to have a copy of that wiring diagram if you find one. Good luck, and let me know how that Haynes works out for you.

you might try gmupfitter.com

or, if you also work on/repair your vehicle, I can recommend getting a subscription to the full-service manual for your truck at a site like alldatadiy.com.  It includes a complete wiring diagram, harness layouts, ground locations, connector pinouts, as well as diagnostic procedures for finding a variety of electrical problems.

 

I also like using my Autel PowerScan PS100 to help with find electrical problems.  Not cheap, but it works really nice and I don't have to fumble with getting both probes of a multimeter in the right spot to get a reading.

Please say you were successful in finding the diagrams. I've searched for 4 days cant find them. I depend on my truck for work and I'm running out of money with it not running. I keep killing batteries. 3 new interstates in one year. Now it kills one in 2 hours. I need help and anything you could share would be a blessing.

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
