well lessee one is heat, 12vp one is signal, .5vp one is return,
all i need to kno is wich one is signal
gotta vom?
one will light up a 12v test light
The 2 white wires are the heater. Makes no difference which way around you connect them, just stick +12v to one and ground the other. The black wire is the output voltage/signal.

's boring but it's something.
Whites are heater. One to ground one to 12V power.
Black is signal to ECM.
