D1 O2 Sensor Wiring
 

Not sure where I found this:

Berfore I get flamed for mentioning Universals.......they were free and I have nothing to lose. They appear to be the same size as the Bosch direct fit though (13927 I think).

I know the Bosch wiring is:

White = heater (+ or - doesn't matter as there is no polarity)
White = (same as above)
Grey = Ground
Black = Signal

but the LR ones are different colors.
I think according to the Elec Manual that it's:

OG = heater (+)
YB = heater (-)
WG = Signal
WO = ground

Does anybody out there know if this is correct? It looks like it from the manual and pinout (see attached) but if somebody knows for sure, I would appreciate it.





GEMS 02 sensor wire colors:

red-12v heater
yelo-gnd
wht-gnd heater
blk-signal

note that these are the sensor wire colors, wire harness wire colors are different (looks like that's what you're listing above)
