I posted this in the crx/ef section already, sorry about the repost, i didnt see this forum.

im helping a buddy with a b16a1 swap in his crx. we're almost done, heres the problems!;
1)his harness has spots for 2 o2 sensor plugs, he only has 1 on the exhaust mani. theres another sensor of some sort next to the o2 sensor, but it only has 1 wire coming out of it, no plug attached to this wire either. its just a sensor with a wire coming from it. What's this wire for and what do we do with the extra plug on the wiring harness? theres another one of these wires where the downpipe is, right before it connects to the cat.

2)does anyone know where we can get a wiring diagram? the vaccuum line diagram we found was a MAJOR help.
