Downstream O2 wiring
Rodents chewed up some of the wiring going to the passenger side catalytic converter O2 sensor. I'm getting fault codes P2270 and P0054 on my 2005 Lariat, 5.4l.
It's not the wires connected directly to the O2 sensor but a wiring bundle of 5 or 6 wires coming out of the connector that connects to the O2 sensor.
My problem is that I have no idea where this bundle of wires originally went to after it leaves the O2 connector. It has been completely chewed into.
Does anyone know where I can get a wiring diagram for the O2 wiring harness?
Thanks,
Mike

Google the year make and model of your truck and "master wire diagram" Most all vehicles have this information online. You can also contact Clymer Shop Manuals and ask for a specific electrical system diagram. BTW it's best to always post as much information on your truck, in your post. Sometimes members will have what you need already. Good luck
