I just bought ProDemand, if you guys need anything let me know. I have the shop version, so 2001 to 2021 trucks just be specific on what you need.

I will ignore any post that wants every single diagram of their car. If you have a specific Electrical issue let me know. 2001 - 2007.5 are mostly the same.

Looking for the wiring diagram for a 2005 silverado, ext. cab... chasing a wiring gremlin i believe is connected to a ground issue so primarily im just looking to see if theres a ground diagram? But otherwise if there is a diagram for the main harness or the fuse block under the hood, that would be awesome..

Like i said, chasing a gremlin.. lol

TIA

I'm not sure where to start but here goes, I have a battery draw problem, park the truck overnight and it will not start with out using a jump box? When I put the jump box on the battery it shows how much voltage is in the battery and it is never lower than 9.5 volts, something pulls the battery down that far and then it must shut off. Just before the problem started the bed was removed and reinstalled, I don't know if this had anything to do with it or not. I don't know if you might have any ideas about it or not but when I saw this thread I thought that I would ask.

We have a 2008 Silverado 3500 Duramax Dually. We are having a problem that we we go down the road with the high-beams on, the lights (High Beams) on the passenger side flicker when you go over bumps. The signal indicator in the passenger side mirror flickers at exactly the same time; when the headlights flick dim, the passenger mirror signal indicator flicks on at the exact same time. We've also observed that the hood latch open indication comes on repeatedly when the flickering is happening. No hood latch open warnings when driving with low beams only.

A couple of other things. We've been seeing cam sensor (or crank sensor) warning code at times as well as a low oil pressure code. We had a scanner run on it and seemed to be generating good high fuel pressure readings (~9000 psi at idle, ~25000 psi when driving).

These problems happen in either Drive or Neutral. We've tried jiggling lots of wires in the engine compartment when in park but are not able to make the problems above repeat.

Do you have any idea where we can look to observe this voltage while driving.
Thanks

Since you don't have RPO Code NW7, just ignore the ones labeled on the pinout (Only for gas). And yes, ABS is linked to cruise control.

At your convenience, I would like to see wiring between the door lock/unlock PCB relay in the fuse block to the driver's door switch (both inclusive) for my 2008 LMM crew cab with RPO AU3 door locks. Those are the most simple door lock switches, just open/close, one of the driver front door, one on the passenger front door. My door locks function just fine with the key, and the key fob, just not the switch on either door. Fuses have no power. i have looked in GMUPFITTER but just don't see what I need there.

Very nice of you to furnish wiring diagrams. I appreciate that.
