PS, if anyone could please snap a quick picture of that fan connector shown above (intact) so I can see the polarity of the wires I would really really appreciate it!

Thanks Lee!

So I finally got everything back together and fired her up today!

Some notes:
The silver bullet fired right up once fuel got back to it.
It runs smoothly, but is idling kind of high, around 1200-1300 rpm...
Still working the air out of the cooling system
No signs of leaks anywhere that I can tell yet, which is comforting considering the heater core mod I did. Only time will tell though if I was successful..
Only code is P0705, which was existing (for over almost two years now....I need to fix the PNP switch for electronic transmission mode selection)
Took it for a short drive around the neighborhood, ran fine overall, and I could hear the pleasant whir of the turbo spooling nicely, now that it can breath again :)

Obviously I will be keeping a very close eye on everything until I am confident I didn't miss something on reassembly, and will test it out on the highway.

Thanks everyone for your input, and to MVS. This site has been invaluable in helping me get through this loooooong task.

I've decided to start another thread documenting my overall progress on the car. Trying to do a total rehab on a budget :)
