Is anyone familiar with Lexus HVAC? 1996 SC400

Trying to find how to over ride all the inputs to allow compressor to operate and take a partial charge in order to diagnose the basic problem.

Unplug the low pressure switch on the receiver/drier, and plug a jumper wire in the electrical connector.

Thanks!!!
