Here's the schematic I drew up after studying the factory wiring manual for the 1989 Astro blower motor circuit. I thought it might come in handy for others.
Although this is for an '89, I'm sure it would work for earlier vans--maybe even newer ones.

1989 Astro 305 with an MSD 6A ignition and a dash-mounted MSD timing control, a 4160 Holley 465 cfm four barrel carb, and an HEI distributor.
Moog 625 front springs and Energy Suspension poly bushings. Rear OEM sway bar. Edelbrock shocks.
As I'm 30+ years as a technical guy, I always LOVE drawings.
Nice job (hobby?)
I was told getting my beauty sleep was a waste of time.
1990 Astro (Z motor) mostly original @ 343,584 miles (552,944.8488960001 Canadian) (03/2008). Bad startup puff. Starting to spray for skeeters. Gone 06/07/08.
1993 Astro with a bad W motor. Parked next to a chicken coop in Talking Rock GA
I'm 'tween Canton and Holly Springs (North NorthWest of Atlanta GA)
I haul bottled water everyday- between 500 and 2500 pounds (226.796185 and 1,133.980925 Canadian) INSIDE the van.
I love the drawings, too, DubyaBee. I almost enjoy an electrical problem on my van...Get to go through the electrical manual, make a drawing for guidance, figure out the problem...
God, do I ever need help.
