replaceing both my down stream O2's with the Boshe universal ones, and I need to know what wires are what i.e. the signal wire from the ground from the two heater wires. I have the FSM but really cant make sense of the diagrams in the book. Thanks guys.

 

I can post the colors from the service manual but you have the service manual. Not sure how I can be more helpful than the service manual.

 

ok just to make sure i have it right then...

Blk=ground
Wht=signal
other 2 are the heaters right?

 

Spend the extra $30 per sensor and get direct plug and play o2 sensors. It will be less of a headache today, and more reliable in the future.
