You will be told that it is passenger side 02 sensor before the cat,, but it is not .. Drivers side right after the manifold is the one you are after.

There are four o2 sensors on this truck. one on each side just below the exhaust manifold, and one on each side behind the second catalytic converters. (just about even with the back of the front doors.

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter
You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks

It is the fuel heater, All you have to do is unplug it.

Testimonial: "Thanks for the diagnosis. It's disappointing that our local Ford service will not advise to help get it running, even to make it in for service."
