Connector for compressor clutch. Belt is slipping or clutch is slipping. Adjusting belt is easy, adjusting compressor clutch isn't hope it's not that.

I have not been able to do anything with it yet, arranging help and a motor bike lifting jack from a mate, hopefully it might get done next weekend.

Nah, just adjust the A/C belt, see Rave it's easy.

Doesn't adjust that much from memory.
Why was it disconnected? Because of the noise?

Probably, as Wammers said, if it's not the belt then it's the clutch.

Sound like the clutch on the compressor is about to give up the ghost and thats why the wire was disconnected

There is a common fix for a slipping clutch. LR did change the wiring (and issue a new loom) to correct voltage drop problems with the original circuit.
But if you take the front plate off the clutch, you can remove a nut and washer from the central spindle, just remove the washer, replace the nut and the lack of washer will close the air gap enough for it all to work again.
It worked for me, and has been working for 3 years now.

Compressor Clutch Failure:
Another common A/C problem is insufficient voltage to the magnetic compressor clutch; as the disk and pulley gap increases with wear the available magnetic flux has to bridge a larger gap. There is an official Land Rover fix for this in the shape of an additional wiring harness which dedicates a new circuit, with its own relay (relay #10 in the engine fusebox), to the magnetic clutch. A quick fix short of this official repair was devised by Andrew Parker. He found you can remove the shim washer from behind the disk and flexure plate (see picture at right by Ron Beckett) to reduce the gap. The shim washer fits to the centre boss of the plate. I have heard from several people who have had good success with this technique.

As this is a 2002 model it will already have the extra circuit from fuse 27, 30 amp through relay 3. Hevac then pulls relay 3 to power clutch rather than doing it direct. Compressor clutch should be adjusted if needed by shimming to give a 15 thou air gap.
