temp sending unit
 

Ok guys, just had my engine rebuilt on my 71 Grand Prix the car is a beast......one problem the guy who built the engine at enginelaboftampa.com told me my temp sending unit wasn't working properly so I'm needing to change it out......its the 3 prong unit, I've looked from one end of this country to the other and can't find a 3 prong sending switch anywhere. I've found 2 prong temp sending units will they work?......is there any other alternative I was told to put me a after market temp gauge. But I really want to keep the car as original as possible.....

The three prong switch is solely used for the Transmission Controlled Spark emission control system. The temp sending unit is located on the intake manifold on a 1971 model.
