I’m new to the forum and this is my first Duramax and diesel truck so I know next to nothing about it. I got a 2007.5 2500HD and wondering if you have the wiring diagram for the rear tail lights? My passenger side stopped working and both of the reverse lights stay on at all times and the brake light and turn signal won’t work on passenger side but when I put on the hazards or press my keyless entry they flash. I just installed a new pair of LED tail lights too to see if that’d fix the problem but still doing the same thing. I’m guessing I just need the wiring diagram for all the tail lights and also the 3rd brake light cuz that’s not working either. Thanks in advance!

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.
Do you have the pin out diagrams for the LBZ c100 and c2 connectors?

I found these while I have been trying to resolve my issues...

The excel document I put togetherher as a shortcut for testing my injector circuits. Additionally I have a picture we took also showing the bail connectors and which injectors were grouped together. They share a common positive and have independent grounds. If you zoom in you can see the cylinder designations we wrote on the connections from testing them for continuity.

@PowerHusler - Im sure your probably busy but I send you a DM to see if you might be able to help me get these diagrams; No worries if not, just trying to save the cost of purchasing two alldatadiy subscriptions.

Do you want the BCM wiring diagrams or connector pinouts? And for what transmission do you need diagrams for? GM or Allison?

I have a 2002 GMC Sierra 2500 HD with a manual transmission. Truck would not start and I isolated it to the clutch position sensor. But a new one in, but still didn’t work. Bypassed the switch so truck starts, but would like schematic for the switch to try and figure out where the underlying issue is. Thanks in advance for any and all help.

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.
I have a 2019 2500 Duramax. I am looking for the Drivers Door "Open" wiring (Sensor) circuit.
If you Could you please. Thanks
