The aircon is controlled by the ECU and the three wires from the gas pressure sensor (item 1202) go straight to one of the ECU plugs. I'm afraid there are no fuses or relays involved. Don't tell me, you have had the system regassed and it still does not work so you are trying to check the sensor by by-passing it?? The wire colours are green, brown, grey. The Meg2 is one of the systems you cannot regas yourself. It is unusual in that it seems to have a high pressure connector (large) instead of the normal small one. It does in fact connect to the low pressure line.

Well pressure sensor changed and no joy, so I'm thinking of buying can clip diagnostic software tool to see what the problem is, seen one £90 on ebay.
