I an finishing my 77 Z28 and have an issue with the AC. The shop manuel and wiring show a thermo switch that attaches to the cylinder head. This switch doesn't allow the AC to energize until the engine temp reaches 95. There is a two wire plug with two tan wires that plugs into the switch. The problem is that GM doesn't show the switch in the parts listing. I tried other parts stores but can find no listing for this switch. Can anybody help/ Thanks, Lew
