Bought a new upper o2 sensor but the clip on wiring harness is melted so I want to straightwire them to o2 sensor.
Here are the pinouts for the truck harness side of the O2 sensors, upstream and downstream. This should give you a sense of wire color and clock location in the plug.
You may need to go to the parts store and take a picture of an undamaged O2 sensor to get things connected properly.
