hi dave,
the white box is the high pressure cut-out for the air-con, they never had a low pressure cut-out switch in it which was bad for seizing the compressor as if the gas gets too low the pump still caries on working but as there is no or hardly any gas going round the system ( which has oil in it to lubricate the piston in the compressor ) it will seize. the wire going to the compressor is the live feed to the clucth to drive it ( when the switch is pulled on from inside the car ) and the other is basically a capillary tube which goes into the receiver drier, where it gets it's signal from to cut it out if the pressure gets too high. the compressor by the way is a york compressor.
the canister behind the ignition coil is a charcoal canister.
