Jim,
According to the wiring diagram in the 70 Plymouth FSM. Pg 8-141

There are only three wires in the harness.

1. 18 ga Light green wire that goes from the switch and plugs into one of the 3 in 1 accessory feed female bullet connectors.

2. 18 ga White wire that goes from the switch and plugs into blower motor (Low Speed)

3. 18 ga Black wire that goes from the switch and plugs into blower motor (High Speed)

The motor must get it's ground directly from the chassis.

I was looking at Alan's blower motor and it looks like his has only one wire (green), so I assume that it is a 1-speed motor.

I've have a 68 Barracuda and 71 Charger (had Challenger) switches and they have three positions; off, low, high. I Didn't know a 1 speed was possible. The resistor is for the two speeds, correct?

This guy at Spring Fling last weekend had a bunch of defrost stuff.
