Alright, made some good progress this weekend. Sautrday, we had to go to the brother-in-law's house so I picked up a couple of small things that I needed. Clutch master cylinder hole cover plate, rear brake line, and a couple of large gromets.
Anyway, I got the dash back in and noticed a couple of slight differences. First, the BII used a goofy relay system for the power locks, where the Explorers use the switch as a manual relay, long story short, I said screw the power locks. But I was able to get the power windows working. There is a grommet in between the door and fender on both sides where I was able to re-route the BII's stock door wiring (which originally ran throughthe fender and popped out behind the head lights. I cut the wire loom down to about 8 inches and fed it through the hole where the gromet used to be and it was a perfect fit. On the drivers side, you have to temporarily remove the parking brake.
After that, I put the dash in. It took me about four times to get everything lined up, the canon plug routed in though, over under whatever it needed, and the right angle on the top securing tabs. After that, I noticed that only the two center tabs on top lined up. The two outer ones weren't even close. At that point I decided that two screws up top should be just fine, as gravity and the angle of these tabs is pretty much what keeps it in place. The lower mounting screw on the driver side bolted right in, and the passenger side (bottom right of the glove box) I had to drill a hole at a 45 degree angls and I use a large sheet metal bolt to secure the dash. Gave it a good shake here, pound there, and confirmed that the loss of two screws on top was going to be fine.
I then routed the rest of the interior cab wiring unger the carpet and back for future splicing of the tail lights. As I went, I removed the BII harness and also cut off parts of the Explorer harness that I didn't need, such as everthing associated with the rear doors, rear dome light, as that fed off the front one in the BII.
Just for grins, I threw the battery in and as soon as I hooked it up, I was happy to see the hazard lights flashing. Cool, that works. Started checking to see what else worked and everything did, even the BII map lights that I spliced in

I thougt no way I can be this lucky, then I turned on the vent blower

NOTHING. So I grabbed the multimeter and I had power on the plug at the blower, but it wasn't turning. I plugged it back in and out of anger I screamed a vugarity at it and threw the screwdriver at it. To my surprise, there was loud wine and what sounded like a dried up maple leaf being chewed up. Then it got quiet and was blowing air just fine. I thanked the blower and gently closed the hood and called it a good weekend.
