The site has gone cold. I had an account that stopped working last month.

They won't answer calls for support now.

Same for me. It worked about a year ago when I was having starter problems, no-go now, too bad.

The GM wiring diagrams for 1967-1994 trucks were scanned and posted to a couple other forums that cater to those older trucks. Those years Silverado and Sierra were trim levels not models.

Mitchell has newer wiring diagrams but they aren't always 100% complete or absolutely correct.
If you intend to keep the truck for a while I'd look for copies of the GM service manuals.
They are pretty pricey new and used for the T800 & T900 chassis.
I'm not sure you can even buy GM service lit on paper for the K2 & T1 chassis.

Has anyone found a site for schematics yet? If not, I am going on the hunt and will share.

I don't want to double the work, but wouldn't mind adding to the info.

Eric O at South Main Auto posted a video on how to find service info.
It's not free but it's not super expensive for the single vehicle DIY stuff either

Depending on what your after, the upfitter manuals have wiring diagrams in them.

You can access those for free.
