I am trying to hook up the wiring for the AC/Heater blower mrotor in a 73 challenger, and I am seeing something that does not make sense. According to the service manual schematic, a dark green wire runs from the motor to connection 4 on the bulkhead connector and a dark blue wire runs to the bulkhead connector 20. The dark blue wire seems to have a ring connector on it which seems to be factory. This would indicate that is it a motor for a Polara or another model. It does power up, my question is will it work as a two speed blower in a Challenger?
Thanks much!
