I am confused about the TCS switch and if my Camaro had one originally or not. My Camaro originally was a 72 Sport Coupe, with warning lights, P/S, manual disc brakes, floor console, non-AC, L65 350 engine, and TH350 trans. The reason I ask is because I am rebuilding the engine and am ready to install the temp sender switches. My assembly manual shows that the drivers side uses a 2-prong temp sender, and on the pass side it uses a single prong temp sender. I guess I want to know if that is the correct setup for warning lights and no AC.
