Well I collected a roadkill a diesel shot at me under my 8. In the process it managed to pull the wires right out of the harness that connects to what I'm assumeing is the O2 sensor in the exhaust. The wires are good and they will pop right back into the harness but unfortunately the colors of the wires change there so I cant just match them up. Can anyone help me on this? I tried my local dealers but no help there.

 

front O2 sensor (in the exhaust manifold) or rear O2 sensor (at the cat converter)?

 

Front sensor. The wires are still intact going out the connection and into the sensor its the other side of connection that pulled out. Any help u can give would be appreciated. Thanks

 

Just climbed out from under it and I was wrong it is the one that hangs down. Found the other on top where you said it would be.

 

Sorry, I mis-interpreted the diagram, gave the wrong colors.

The diagram doesn't show what colors the actual sensor side of the connector is - and it's probably those that pulled out.

The wires from the ECU, as you look up into the open terminal side are -
yellow - top right
blue/red - bottom right
red - bottom left
white/red - top left

The wires are still in the sensor and they are intact into the harness. The wires that pulled out are from the other side of the connector so you may have it right.

 

the wires on the sensor side are different colors that the wires on the harness side

 

If the sensor wires are still in place, the above colors should do it. Look at the connection side, where it makes contact, and work clockwise.
