A few random questions (that I didn't find answer to in the FAQs)

I've been digging through the forums to try and find an answer to your switch question.
I did find this cool thread;

Can't help you with the thrift air, because i'm balling big with the deluxe heater ;-)

There are wiring diagrams online on this site and all over, just keep looking. Google image search is amazing, hope this helps.

Those are the diagrams from the shop manual. What is missing is the wire color. I have a couple random wires hanging under my dash that I'm trying to find a use for.

Thanks. I searched "thrift air" and didn't find this thread for some reason.

That thread has a lot of interesting ID and parts interchange info, but nothing on this switch. So I did what I should have done to begin with and broke out my Fluke. What I found is that both B and C terminals close the circuit with the L, M and H terminals. What I'll do is power B and cap C somehow.
