Marlin,

After reviewing my '70 Chassis Assembly Manual, I realize I need a "water temperature switch" to complete my TCS system. I thot the extra wire/connector in my Nova wire harness on the passenger side of the engine bay was for the factory temperature idiot lite (or gauge as appropriate) in the cockpit (I am runnig aftermarket vintage SW gauges including a water temp gauge). It is a green wire with the "L" shaped/ 2-prong connector. I need a source for the Temp Sending Unit that it correct for this application . I believe the sending unit goes on the pass. side of the block between the two rear most spark plugs (using Charley's '70 Z28 website as a reference).

Thanks,
