One wire will connect to the same wire as the Old O2 sensor did.

The remaining wire connects to ground.

Make sure you connect the correct wires to the correct places.

I would think there are other board members that have good information on this. Maybe even instructions, which came with theirs, they can post.


These sites show how 4 wire O2 sensors are wired on newer vehicles from the factory.
