well on a late night drunk expedition on my buddies farm i somehow ripped the o2 sensor wire off at the connector...dont have the one half or it....what color wires in the harness down there correspond to the color wires of the sensor ?? 90 w/ a 3.0 v6 any help...thanks in advance

 

On my 91 facing the harness plug with the locking tab up I have white/red at top right, pink/green at top left, brown at bottom right and black at bottom left. Hope that is clear. If not I can try and take a picture.

 

but those color wires match up to what color wires on the sensor ?

 

black to blue, brown to white, pink /green to black, white/red to black. The two black wires on the sensor can be interchanged.
