My O2 plug is not connected to the sensor...more like it won't connect. The mani plug looks like this (- -) and the harness looks like this (=) or maybe the other way around. Can I rig this wireing up until I can get the proper part? My motor is running, but gas mileage seems to be REALLY bad, but that might just be me. Anyway, let me know what you think and I'll see what I can do. Thanks!! -edit- before you ask which harness they used...I'm not quite sure if its off of a B series or a D series. Sorry in advance. And for you guys that don't know...its a 99 hatch with a 99 JDM ITR motor.
