I am trying to rescue a 1982 Silver Spirit that was being sold for parts. I finally got the car running after new fuel pump, filter, fuel injectors, fuel distributor rebuild, warm up regulator fix, new belts, tranny contact clean, etc. But the temperature gauge does not read anything - never comes off bottom of gauge. I can not tell from the diagram in rrtechnical page M17-24, where the sender sensor is for the temperature gauge. I notice that on top of the thermostat housing there is a 2 pin plug with nothing plugged into it, but there is no loose connector nearby. Can anyone tell me where the sendor unit is located ? If on top of the thermostat, does anyone have a picture of this connection ? Thanks.
