2002 chevy s10. The a/c low pressure switch has three wires. Which wires do I need to jump to bypass the switch so I can charge the system? I do not have a factory service manual available at this time.

do not jump this system. add some freon to start. there should be enough pressure to close the switch and start it to cycle. if it does not, there may be another failure in the system
