I think we can all agree now and put this " simple " thread to bed, Pin 3 is usually already occupied on an early 66232C as it is used as a supplementary heater via Pin 3, leaving Pin 1 as the spare pin to be used as the parking heater with a remote, but with this model both pins take 12v so doesn't make any difference and will work from Pin 3 which Les says is empty and he has already tested
