You'll need to change your O2 to a "skinny type" for it to work. Harness doesn't neet to be repinned.

I believe it's the same sensor off a z31 non turbo. The parts thread only lists turbo model 02's which are the "fat type". Maybe search around or start a thread asking which o2 sensor is interchangeable with the redtop (skinny type) o2 sensor.
