can someone direct me to a 1993/4 wiring diagram for engine inc. compressor pressure switch connections that will need to be changed when I retrofit this to an 84 on 134

thanks in advance

thanks pl
it appears to be the only pressure switch on this set up as there are none in the hoses as in the later 134 set ups, it appears to be just an earth for the clutch that breaks if pre-set pressure is reached, anyone any idea where I can get one and the pressure relief just above it needs upgrading from r12 to 134, looking now for a uk based sanden agent who will supply parts as req. if I google its 10,000,000 ebay links
