After changing the rear bank plug wires on my 3.8L V6 I followed a wire headed to my pre cat O2 sensor. A excess blue connector seemed to be spliced into the O2 sensor wire with no where to go. o2 sensor and main 02 connector didnt seem to plug into anything that was missing a plug. Cant post pics on here but it is a two prong blue connector. Seemed to look similar to the connectors going into the rear manifold. Any clue what it could be or where it could go?
