Tried too follow the wire off the upstream O2 sensor from the header back too the connector, however, it seemed to trail off into the abyss of somewhere I can't reach. anyone know where the connectors are located for these buggers? or did dodge design them so their a PITA to change?

Which side was it on? The passenger side is almost up by the valve covers if I remember right, and the drivers side was up on the transmission. The connectors have zip ties on them so its a pain to get them out of that "abyss." Good luck!
