If the exposed wire or connector is the problem why do you believe you need to replace the clutch /coil?
Have you done a resistance test on the coil itself?
A/C Compressor Clutch Coil Test

Compressor isn't locked up, I can spin it by hand with no issues. If it happens to be something other than a short, what else would cause the fuse 10A to blow? It'* not low of refrigerant, no leaks.

If the wire harness is in good shape then yes the compressor could be pulling too much amperage at times.

Here is a schematic.
Also check your ground connections at the transmission to engine. Should be 2 or 3 ground wires at the stud near the starter.

UPDATE:

Thank you everyone! I went ahead and just replaced the clutch by itself. My AC now blows cold! Much cheaper than replacing the whole compressor ($600) it only cost me $40 to replace just the clutch! Went to dozens of shops and most kept telling me they don't make just the clutch. (I showed some the clutch started making other excuses lol) Those diagrams and clutch assembly really helped me! Thank you all!king:

also verify that the fuse is correct , correct amperage and whether the fuse is a fast acting or slow acting. When motors/ clutches start up they appear to the circuit as a short for a very small amount of time. A fast acting or a lower than specified amperage you would see the fuse open, if the circuit calls for say a 15A fuse or a slow acting fuse that could sustain momentary surges in current then no open fuses. ...:::NOTE:::... I AM NOT SUGGESTING TO USE A HIGHER AMPERAGE FUSE OR SLOW ACTING FUSE IN PLACE OF WHAT IS SPECIFIED. Just make sure you are using the correct fuse.
