I can avoid this problem if I can regain the defrost function to blow outside air onto the windshield.

You won't get real defrost without AC (correct?). Better than no air at all though.

Sorry about my manners - welcome! Very nice looking car you have there.

The first pic is a view of the left side of the tranny/engine assembly--the sensor has been circled. If you follow the wire in the second pic, you'll see that the plug is located in the engine compatment, under the heater blower. There's a bracket with three similar plugs--the flywheel sensor is the middle plug.
