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.
