So I need some advice on where to go from here. I had work done by a buddy to replace my upstream drivers side o2 sensor plug. It burnt up, shorting out, causing fuse 32 to blow. That which throws 8 different codes and causes limp mode. I cut the burnt off and was going to replace with a after market but all of the wires and melted together from the tape. I have no clue how to proceed and I cannot find online the whole wire set to just change out.
Didn’t end up connecting the new plug because I can’t even get power to any of the 4 wires. No clue, gonna try more tomorrow and see if I can’t chance a issue down, or if a reply comes out of the blue and saves me!
You definitely have a blown heater fuse for the o2 . What you need is to print out the o2 normal connections if you are putting new o2's in then you need to get drawing that came with new o2's to match up wire colors . It helps to ohm out heater wires to identify them . Which side are you working on drivers or passenger side .
The sensor is the one with the arrow thru it . You have 4 o2 sensors the important ones are nearest engine before the cats
Ho2s 11 is bank one passenger side the first one from engine . Ho2s 21 is bank 2 drivers side first one from engine . example 11 heater wires are both red sensor wires are both gray .
Ho2 passenger side 21 is more complicated heater is yel/lt blu stripe ,red with /yel stripe . sensor is red/black stripe, gry /red stripe .

Sorry, don’t really know how to do just a @ or reply. It is drivers side upstream, so before the cat. The last picture is all four wires but they have electrical tape melted to them. Cannot tell any color of them, aswell as no clue how to physically track them up to see why I am not getting power to it
Mine says fuse 32 in passenger kick panel. When in doubt check them all .
No I already checked that, I know that is the fuse. That is the “reason” for that fuse to blow. I just replaced the fuse and tested, still no power to that o2 wire. So now I need to find the rest of those diagrams to see what relay it goes to and see if that is working fine.
