I snagged a harness from a later model Blazer at the local Pick&Pull. Carefully removed the plugs and wires from the doors along with the rubber boots. As I remember, the harness went into the cab/jamb to a connector. The harness went from there to the firewall and fuse panel. Someone had already removed the dash pad, cluster, glove box etc, making the harness more accessible.

I have everything installed in my truck and taped off the connectors in the doors as I'm still using manual lock and windows. I have all the other parts, window regulators, lock solenoids, switches etc. One of these days I'll buy a pair of new window motors and a pair of these switches.
