Took my E86 to get aircon regassed as it was not blowing cool air. Aircon people tell me its fully gassed up with no leaks evident however AC clutch is not operating. Checked fuses and green wire to fan but no luck. Closer inspection of the compressor reveals wire stripped bare (see pic) although apparently still connected. Could this be the culprit? any advice welcome including how to replace this connector. Thanks

Chances are that wire is the culprit.
Here's what I used to do in the good old days when I did this stuff for a living....
Get the connector off the clutch. Run a piece of wire from a guaranteed permanent live (battery is the best obviously) and touch that on the positive 'prong' of the clutch. Make sure you have a good earth too! If the clutch is sound you will hear a loud click and you can see the clutch assembly move if you look hard enough.
If it clicks then that is your problem. If not then check the High Pressure switch (cut into the small A/C pipe), then the Low pressure switch (cut into the large A/C pipe). 99% chance it will be one of those three, but my money is on the clutch wire.

The wire is the electromagnetic clutch feed and is prone to loading its insulation but as it's so short it doesn't get too close to anything grounded. You can use this to run 12v to as Pondrew says.
You can also use INPA to read if there's an open or short circuit situation as they come up as error codes.
