Hey guys, im in the process of installing a b16 into my da, and im trying to get wiring staight. my problem is im having to make one wiring harness out of two that I have. the issue came when i tried to wire up the o2 sensors. the b16 has two on the header, but im not sure about the ls setup as my da didnt come with an engine. My question is, does the ls have two o2 sensors or 1, and if it does have two?, what color are the wires connecting them. I know one is white, but what about the other. On the b16 wiring harness one is white and one is orange. but on the ls harness one is white and the only wire i have left is (black/white). where does this wire go? (Black/white)Lastly, do i have to run the second o2 sensor? Really need this help guys, so fill free to offer some advice.

peace,
