Hooking up a GM heat O2

[Nish Limaye]

Does anyone know the pinouts on the Heated O2 GM sensor? When I look at the connector I see the letters C, B and A.

Looks like C is the purple wire that carries the O2 signal. B and A are the power and ground, though I am not sure which is which....

A=? and B=?

Thanks,

As long as you get the purple wire on the signal, It doesn't matter which is + or -.
