1997 Dodge Caravan A/C LOW PRESSURE CYCLING SWITCH

MY MANUAL SAYS THAT IF THERE ISN'T ENOUGH REFRIGERANT IN THE AIR CONDITIONG SYSTEM THE LOW PRESSURE RECYCLING SWITCH CAN BE SHORTED TO ENGAGE THE A/C CLUTCH SO THE SYSTEM CAN BE CHARGED
PROBLEM -
1. I CAN'T FIND THE SWITCH
2. IF ITS WHERE I THINK IT IS, I CAN'T ACCESS IT IN THAT PART OF THE ENGINE.

FROM LOOKING AT THE WIRING DIGRAMS IN THE MANUAL IT WOULD SEEM SIMPLER TO SHORT OUT THE CONTACTS OF THE A/C CLUTCH RELAY. THE DIAGRAM SHOWS POWER IS SUPPLIED THROUGH THE RELAY TO THE CLUTCH WHICH IS CONNECTED TO GROUND - I CAN PARTIALLY REMOVE THE RELAY TO ACCESS THE CONTACT CONNECTORS WHILE LEAVING THE RELAY INPLACE - SHORT THEM AND ENGAGE THE CLUTCH
IT SEEMS SIMPLER, AM I MISSING SOMETHING?
