I have looked over my service manual and can not find the two wires that leave the heater motor. The Dark green one goes to a resister, on top of the heater box. The other wire ( Brown) has an eyelet very close to the motor, with two wires, both Brown, may attach to the clamp for heater tubes through the firewall? The other Brown wire that comes out of this eyelet is long and can easily make it to the dash bottom and over to the radio area, it has a round ring eyelet at its end. Have been looking at it and going trying to retrace things, I just don't know where it goes. This is a '69 Dart Swinger, no A/C. Have tried to take a picture in there, the red connector is simply a butt connector
