I'm guessing yellow but you can make sure by going to lt1swap.com and looking at the PCM pinouts for your vehicle. You also may be able to tell by looking at the O2 that's on the other side, the wire that's a different color is the signal wire. driver side front is bank1 sensor1 back is sensor 2, passenger side is bank 2.
