1100 GS O2 Sensor Wires

ruskinrowe · Oct 24, 2011

Hi,

I just bought a universal O2 Sensor that's got white, white, Grey, Black Wires.

I need to chop my plug on my GS and Crimp a new plug on for the universal sensor.

My Original BMW wires are Green, Brown, Brown, Black (With Yellow Inside the Black sleeve).

Anyone got a clue as to which ones go where? I am guessing the Brown Brown translate to White White but Dont know what to do with the Remainders.

My 95 Model also has a CO Pot, and a Golden Yellow CCP Plug. (Pins 30+87).

Thanks,

Thanks, that's a great help. Guess I need my meter out. One brown is ground on is 12v+.

Yellow shielded = black.
Brown earth (-) = grey.
Brown pos (+) = white.
Green = white.

Thinking about it again,
I have the CO POT installed, so I don't need to connect the o2 sensor. I can get my meter out and read the output voltage of my sensor (disconnected from ECU) and "tune" the mixtures with the CO POT screw under the rear seat.

Am I wrong?
What voltage do I like to read from the output? I recal 1.0v is rich, so 0.5-0.6 would be perfect?

Not sure myself, I run the O2 probe without a pot so the bike does everything... I just adjust the tps to 'tune' things.

O2 Sensor Connected to ECU now. Getting 0.355v Readout from the Signal Line at 2000rpm. Seems all is Good.

Thanks for your help again.

try to set your tps for 0.371... I find I get the best performance from this.
