I plugged it into the heater core coolant in line and ran the wires to the dash and installed on one of these on/off/on switches... https://www.amazon.com/gp/product/B012MY...UTF8&psc=1

That ball valve replaced the manual factory valve under the hood. Now, when I want ice cold air, I flip the switch down and then off. This will shut off the coolant to the heater core. If I want warmer or hot air, flip switch up and then to off for heat.

This was the final piece to the puzzle in this lousy ProStar AC system. I installed this in May of 2019, still working, knock on wood.

Been there done that I think when you originally posted it since then I replaced that valve with the stainless steel one and sealed the case better I git corrosion inside and it died
