For the standard heater, just where is the heater motor switch supposed to be? And what does it look like? I think I have the stock switch, which is a three position switch. It has the low speed dropping resistor mounted on it (ceramic tube with wire wrapped around it). I think it mounts under the dash, just to the left of the steering mast. I don't like the idea of this resistor near my knees, as the thing will run hot on low speed, especially considering I'm running with 12V instead of the stock 6V. Maybe I will just eliminate this resistor...don't need the heater too often in south Texas. Not sure if I have the 6V or 12V motor, I assume I should use a 12V motor which hopefully is an easy replacement.
