Add an R-134a discharge port, and a high low pressure switch without modifying the system. The adapter screws onto a high side R-12 switch port, the old valve core has to be removed. The switch includes the wires, which splice into the wire on the compressor. The pressure switch operates at the pressures listed below:
High Cut in 23KG / high cut out 31.4KG
Low cut in 2.0KG / Low cut out 1.5KG
This adapter is designed to fit on 3/16" port. This port will be smaller then the low side port. If your ports are the same size use part number: 119-9914. If you are not sure what size you have try fitting the cap off of the low side port onto the high side. If the low side cap is too large, this is the correct part.
