Hi,
I just finally fixed/hacked the auxiliary heater connections and everything seems to work but what I don't know is the polarity of the connections to the heater motor. No matter which way I connect the wires, the motor it will run.
See the pix:
Is the yellow (+) and the brown (-) or the other way around?
I thought I would feel the warm air coming out the vents when the right connections were made, but it's more like a breeze either way so I can't truly tell (kind of feels the same)
I did notice that one way ( (+) to brown and (-) to yellow) ) the motor makes an awful noise. I just hope this is the wrong way otherwise the motor is shot.
Thanks
