jrunner Posted November 8, 2009 Share Posted November 8, 2009 1983 280ZX. What is the electronic round switch with two terminals behind/under the Air Regulator on the intake manifold? Also the two blue wires connected to this switch, one yellow stripe and the other has a white stripe, what is the correct color code connection to the switch?

trippintl0 Posted November 8, 2009 Share Posted November 8, 2009 I think the one you are talking about sends a signal to automatic A/C to delay Heater operation until coolant is up to temperature. Quote Link to comment Share on other sites More sharing options...
