I have one from a 06 RSX TypeS w/14k miles.. Butttt the instead of my lazy/brain dead friend unplugging it when he removed swap, he clipped it.. It can be yours for cheap and all you have to do is reattach with butt connectors..

 

Using butt connectors on O2 sensors doesn't work. They are too sensitive and the connectors alter the resistance too much.

The best price I found for new O2s is Amazon. just look up the part number and type it in.

 

I have a working one. But without the plug. But the pins are there. All you gotta do is plug the pins into your old plug.

 

i cant find a pin out what so ever! and the colors on the male side of the connector is different colors. i dunno what to do my 2ndary o2 has been gone for 2 months
