The individual sensors should have the same 4 color codes in the pigtail. Unless the wire length is different, they will work on either side.

As far as the truck harness goes, the connector with the gray/light blue wire is #1 (passenger side) and the one with red/black is #2 (driver side). The other 3 wires in each connector are the same color codes on both sides.

I guess it don't matter which side o2 sensor plugs in bank1 or bank2 . Are you sure of that? I don't want to mass anything up.Thanks GTDad

The sensors themselves can go on either side IF the wire lengths are the same (not every vehicle has equal length sensor pigtails though).

Each truck harness connector MUST go to the sensor in the correct bank. If they are crossed, one bank will go full rich and the other will go full lean. Just use the color code directions I gave in the first post and it will be right.

Bank one is right ( passenger ) side.
