black and black are grounds...
white I think is power to warm the sensor up and green is the signal wire... I think

are you goin to hook up A/F guage?? if yes then go with the white...black and black are heater wires....so u dont wanna mess with that....i used the white...u coudl try it urself..jus splice a lil off the white one and test it...while the car is idle...nuttin is goin to happen dont worry...so yea..black and black is heater wires...white is sensor and green with i think a black strip running along it is for the signal..

im not hooking up no gage.... i rplaced my o2 sensor with a bosh one...

does the Bosh unit have a plug on it ? if so the plugs can only go together one way... don't worry about colour codes...
