2008 5.4 passenger side upstream 02 sensor plug coming from main harness melted to my manifold. Can the wires be connected directly? From 02 wires are black, grey, white, and white.. From the main harness wires are red with white stripe, red with yellow stripe, grey with red stripe, and brown... No idea what goes where....... Any ideas???

 

I suppose you could but a new one costs about $45 dollars form the outfit below.

The plug coming from the main harness is shot.. Nothing left but the wires so buying a new 02 wouldn't help. Nothing to plug it into. Will have to wire in direct. Prob is the 4wires from 02 go to the 4wires from main harness just don't know which hook to which....

 

Oh I see, Go to a Ford dealer with your VIN number and ask about a replacement jack. You can be sure you are not only one who has had this happen. they should have a new one that can be spliced into the wiring harness. This is one of those kinds of parts you are likely only to find at a dealer.

 

Will give them a shout. Thanks

 

I checked and what they will have is a Oxygen Sensor Harness you don't have to splice anything this replaces the whole thing.

 

Good deal. Thanks
