I'm in the middle of installing a bosch OEM O2 sensor and I'm having a bit of trouble. The wiring conversion chart doesn't seem to have accurate information on how I should splice the wires back together. My original sensor, which I'm pretty sure is stock, is a bosch and it has red white and black wires to the harness. Which one is the sensor, ground, and heater?
Also, I'm confused because the new sensor that I'm trying to put in has two white wires and one black. The instructions are talking about a grey wire but there is definately no difference in color between these two whites. Whats the deal?
Thanks again guys!
