I have a 96 civic cx and the catalytic convertor i'm putting in for my swap has a secondary O2 sensor. Trying to find out where the damn connector is for it. The originial motor doesn't have a secondary O2 sensor....i believe, just the primary sensor.I looked underneath the car of course and I found an inlet which I see two wires. But the thing is the wires don't budge. Anybody know if I have to wire up a secondary O2 sensor or should I take some tweezers and yank those yellow wires?
