O2 Sensor Routing
Question on routing the downstream sensors: do they connect to the harness connectors up by the headers on the same side, or do the wires for those sensors cross over? That is, does the right downstream sensor connect up by the left header, or by the right header?
Or does it really matter?

Fronts plugs into the same side, i.e., left to left, right to right. Rears plug into opposite, i.e., left to right, right to left. Plugging the fronts wrong can lead to a lot of codes.

Thanks guys, I think I have it sorted. I think I crossed front and rear on one side, so I was getting Bank 1 Sensor 1 and Bank 2 Sensor 2 codes. Don't know why they don't use different connectors for the sensors so you can't cross plug them!
