I've added a new database to the website for wiring diagrams, pinouts and schematic PDF files for some GM vehicle modules. Over time, I'll update the content as needed.

The schematic section can be found in the top header menu bar under "GM CARS INFO & SERVICES" GM Schematics.

Note: The wiring diagrams, pinouts, and schematic files are only visible to +Contributor members. To know more CLICK-HERE.

Yes, but I need to figure out how to give you access to add content, as it's currently set up only for admins.

I added you as a publisher to the GM schematics section. You can submit content by clicking the "Add GM Schematic" button. The only issue is that only the admin can add categories. If you tell me the category names that you want to submit files under, I can add them. For the PDF files to auto-display, just drag them into the editor, and after you click submit, they will auto-display.

I have all of the schematics for the 2005-2010 Cobalt. How can I upload them?

I paid for these but I understand....

I have a Silverado EV and was able to get a load of schematics from the AC Delco site the other day. Please reach out if I can be of assistance.
