Need to replace o2 sensor plug that goes to main harness

itechteam · 09-24-2024, 04:35 PM

2010 BMW 335i M, stage 2+ MHD tune. Catless downpipes.

wide band o2 sensor plug somehow hung down and got wacked by something. I found a plug online that fits the female side that goes to the o2 sensor.

The wiring on the car to main wiring harness has yellow, green, white, black. The plug I got is white, white, grey and black.

I get black to black, and I am assuming the 2 whites on the plug I got are for the heater, but don't know which wires to connect to from the o2 sensor its self?
Any ideas.
