I have just finished rewiring the whole car, it was part of a complete 2.5 yr rebulid. Most of the wiring and relays are behind the guards now, much neater.

One wire has me stuffed though. Its an Aircon wire, and went to what appears to be a pressure switch in the aircon line, about 1.5 ft forward of the dehydrator.

I have searched the manual everywhere and cannot find any reference to it. Its a grey wire that goes into a two pin plug, the second wire goes straight to earth, thus the reason i believe it is a pressure switch.

I can only find two pressure switches in the manual and both of those are accounted for. So where does this third switch come into it? Or is this some strange modification done here in Australia when it was converted from Left to Righthand drive?
(edit for grammer)

 

got a picture of it?

 

No I don't have a picture, but to give more of an idea

The plug is exaclty the same design as the one that fits to the top of the compressor, Hope this helps
