Are you sure theres 2 whites, im sure 1 is white and 1 is beige. The black is the earth, iirc the white is the only one that goes to the ecu.

no theres 2 whites 1 grey and 1 black,,,


im not entirely sure as to there uses i think the 2 whites are for the heater,, black is earth and grey is signal

all i know for a fact is when wiring them up,, it dosn't matter which way round you put the 2 whites
