Oxygen sensor connector locations

Here is how the O2 sensor wires are used on my '92 Stealth TT. Terminal assignments on the connector from the sensor as you are looking at the exposed terminals are 1 at upper left, 2 at upper right, 3 at lower left, 4 at lower right.

Black (terminal 1 on connector) is B+ for the heater
Green (terminal 2, might be a white wire on newer models) is ground for the signal cell in the sensor
Black (terminal 3) is ground for the heater
Yellow (terminal 4, might be a red or blue wire on newer models) is the signal wire (~ 0-1 v)
