My car: a 1992 non-turbo 2-seater hardtop. While searching this forum did Identify the two probes at the rear of the Catalytic converters as Catalytic temperature sensors, and why they're there. Searching failed to show a wiring diagram and My Factory service manual (two book set) doesn't seem to have it. The ECCS section, EL section and Schematic fold out does not show them. I have downloaded 1990, 92,93,96 F.S.M, but they don't seem to show them either. I don't have problems with the sensors, I just would like wiring diagram for them. So does anyone have wiring diagram for the catalytic temperature sensors or point me to the page?
