TRINARY SWITCH WIRING:
Ed sent me some really detailed text about how to do this but I still was not 100% sure of myself. This video explains with pictures what is really going on, and with this and Eds explanation, it was able to make its way through my thick skull. Hope this helps others.

This is excellent! I'm really close to starting my setup. I'm going to get the p/s and hydroboost brakes done first and then work on the a/c. Thanks for all the fine pictures and you've given me a lot of ideas!

The a/c system is charged. I did it at the house and believe it is really close to the 28 ounces, Vintage Air recommends. If anyone wants to comment on these numbers, I would like to hear your opinion.
Ambient air 84 F
humidity 80%
L/side 15
H/side 210
40 F out of center vent med blower speed
This was at 1500 rpm, with a fan blowing on condenser.

Just sitting at idle with no shop fan blowing on condenser, 30/35 low side, 225/240 high side. The electric fan would not come on unless I blocked the front of the condenser with a piece of cardboard. Once the high side pressure made it to 254, the fan kicked on until the pressure went down to about 210. 40 F out the center vents.
