very nice

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.

Hatzie, thank you for posting and me maintaining these.

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.

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...

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 am looking for these two (1996-2000 GM STG 6.5 Litre V8 Turbo Diesel Engine (DS4 OBD II Electronic Fuel Injection Systems) & 1981-1985 GM STG Oldsmobile 5.7L 350DX Diesel Engine. Can anyone provide a copy?

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.

Hatzie ,

Big THANK YOU for all your hard work.

I also have an 03 Silverado 2500HD 6.0L 4l80 2wd are there any parts or service manuals available for these?
