You can print the wiring diagrams at Fedex Office. You need to get the attention of the counter staff to print banner pages like these. If you ask nicely they can enlarge to slightly larger and wider pages. I would suggest doing it in the wee hours at one of the all night locations like Downtown Salt Lake City.
I'm going to re-scan some of the less than perfect wiring diagrams at higher resolution on the newer scanner, that handles 120" long pages in one shot, over Christmas this year... I HOPE...

Just downloaded the 78 wiring diagrams to a USB stick. This PC is running Linux so I wouldn't assume my virus scanner would find Windows bugs. I checked the file with different virus scanners on four different windows machines and I'm not seeing any untoward attempted network traffic through the firewall from my guinea pig, Sitting Duck, where I opened the file.
No virus found by the software on the windows boxes.
I believe Mediafire does a virus scan on incoming files to avoid being a virus distribution hub.

That being said. It's the wild west out there. Ad servers are becoming virus vectors. That's why I run script and ad blockers even tho I'm running my own distro of Linux that has a low probability of infection with your garden variety Windows viruses. Android is Linux based and there are inroads by the malware creators into that ecosystem so I'm not saying that "Linux can't be infected". It most certainly can and viruses do exist for my OS.
I air gap the machine by unplugging the network cable when I'm not using the network.
I would highly recommend getting NoScript for Firefox and only temp whitelisting the minimum URLs to make individual web pages work til you get a handle on your comfort levels with various servers.
I largely run Firefox because Chrome tends to neuter ad and script blockers (no big surprise, Google is funded by advertisers) and I don't run the Microsoft or Apple browsers so I have no idea what's available for Safari or Edge.

Re: PDF of Square Schematics & GM Training Manuals

It came to my attention that the 1989 RV service manual link was pointing to the 1988 service manual.
I just fixed that problem for anyone that needs it.

Re: PDF of Square Schematics & GM Training Manuals

Hatzie -

I am working on a 1989 Full Size Blazer (K5?). Would the 1989 RV-P wiring manual be the correct one to use or is there a different one? It looks like the truck only and no Blazer or Suburban items...

The Blazer had a dash fire and destroyed the SPID and everything under the dash and most of the engine compartment. So I am not even sure what options are on this thing yet...

It's for the R V & P series trucks. Suburbans and fullsize Blazers are R V series.

The table of contents says Page 50 is rear AC. Pickups don't have that.

You should be able to liberate the engine bay harness and or cab harness from a pickup and marry the Blazer specific cab wiring (Courtesy lamps in the mirror and RH visor, dome, tailgate power lock, tailgate power window) into it without a lot of trouble.
Get some painters tape and a sharpie. Take a bunch of pictures too. It'll slow you down but forgetting where something goes or where it's routed will slow you down more. ;-)

The phantom view of wiring harness runs in the 1990 & 1991 wiring manuals should apply to 1989 and for that matter most of the 73-91 squarebody trucks.

Re: PDF of Square Schematics & GM Training Manuals

Thanks for the tip on the phantom views in the 1990-1991 manuals. That will help with this rebuild. As for marking wires in the existing blazer that's going to be hard to do with this one...see pic below...

Re: PDF of Square Schematics & GM Training Manuals

You may be surprised about what survived. That's not a bad burn at all.
Your courtesy wiring for the visor and windshield mirror, if you have it, may be damaged.
The power door wiring is likely OK up to the kick panel and possibly beyond. The LH door card looks like it took the brunt of the heat.
The dome light wiring is along the floor and comes up under the fuse panel so most of it is likely just fine. Power tailgate wiring is likely the same til it enters the dash.
The rear lamps and fuel tank wiring are not in the cab. They're wired to the bulkhead plug in the engine bay.

Get the harness from a 1989 SUV or RV 3500 pickup. The 89 Suburban or Blazer will be more plentiful.

I have both but life has gotten in the way.
I haven't had the time to scan them.

Hatzie, thanks a lot for publishing this info. I've been referring Facebook folks to your thread over and over again when wiring questions come up.
