Great offer. It's just about a necessity to have wiring diagrams for any electrical problems.

 

Thanks for your offer. I am looking for the wiring diagram for a 2004.5 Chevy Silverado 2500 HD Crew Cab Duramax LLY, specifically the power to the OBD2. I have 12 volts at the cig lighter, but only 4 volts at the OBD2.

 

That seems to be a common problem with the LLYs. Anyways here you go.

 

Thanks for the diagram. Do you know the location of the C1/D5 splice? Is it in the dash, or beneath the under hood fuse block?

 

Someone request ground distributions points for a 2016 chevy duramax LTZ.

 

Absolutely fantastic - thanks - there's a good chance you've saved me dozens of hours of troubleshooting.

 

That shouldn't be a problem, personally I would just tap into pin f on c1. It's hot at all times. just to make it easier on yourself.

 

Can you help me find the location of the dome light wire to wire up my strip lights for courtesy light? Thanks! I've been searching for hours.

 

I know it's an old thread but can you still help get diagrams? Need complete transmission/transfer case diagram and pin out. Or if you can a complete diagram of the truck. I ripped the wires out because the company "mechanic" didnt tie the wires up. It's an 03 3500 HD 4x4 a/t 6.6 lly. Not the original lbz.

The power to pin 16 on the DLC comes from the same source as the cigar lighter according to the wiring diagram. Do have 12V at the cigar lighter? Have anything plugged into the cigar lighter? Charger? Radar Detector? Gum Wrapper? If so, unplug it until your problem is solved.

#45 CIG LTR 15A Cigar Lighter, Data Link Connector (DLC)

Make sure you have power coming out of this fuse. Pull the fuse and make sure you have good contact.

 

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.

Do you have the wiring diagrams for an 01 LB7 coolant censor had the neighbors dogs rip out the wiring harness and a ton of wires on my truck….

 

Take a picture of the of the spliced wires. I don't understand how a dog rips greasy wiring harnesses from on top of the engine bay.

No problem. I have the diagram pulled up now, but will wait, since it's a bit late at night and stuff needs to get done early morning.

 

What started as a problem with some mouse chewed wires under the hood and a bad taillight and turn signal has turned into a bad Body Control Module that still didn't fix my original issue of the taillight and turn signal. Fuses all checked out. Next step is all the wiring, bumper to bumper. Could I possibly get the complete schematic for a 2013 Chevy Silverado 2500HD 6.0?

 

Complete diagram? No, sorry. But if you have anything specific I'll try my best.

I could really use the TCM pin #s or the TCM wiring diagram for a 2004 LLY At the TCM & at the plug on the back of the transmission . trying to figure out an E shift silinoid electrical open circuit. Any help would be appreciated. Thank you.

 

It would be great if we could get some information on an lbz 2006 sierra from the bail connector to the controller. I have replaced the wire harness and all the injectors and can't clear the 0201 0204 codes I know they are tied together on the engine harness which is brand new. We swapped injectors and repeat the issue so we have eliminated the possibility of a bad injector. Now we are about tobchase this common wire down on the truckbside of the small bail connector. Thanks in advance.

 

Any chance you would be able to get a diagram for the parking brake on a 2021 chevy 3500 HD?

I have a 2021 Silverado 1500 with 3.0 Duramax
I’m trying to add a set of factory power assist steps
(I think that’s what they call them) Running boards

My truck didn’t come with them and I’m trying to find the connection points I need to tie into to make them work. Do you have the ability to see the diagrams for this?
Also I have a VIN of the truck they came off of that did include the wiring if that helps in any way.
From what I’m finding trucks that came with the steps have a chassis harness labeled as option BRS with code of J305

man I would greatly appreciate any help you could offer!!

 

Do you have wiring diagram for the rear lights and ground points. Rear running lights not working.

 

I am looking for the wiring diagram for a 2006 Chevy Silverado 2500 HD Duramax LBZ. Can you help me with this please. Thanks a lot!
