What controls the temperature gauge on a 1990 ford f150 5.0 engine and where is it located

The temp gauge on the dash displays the information transmitted by the coolant temperature sensor. This sensor is located - on the engine - by the water neck. The water neck is where the top radiator hose comes across and connects to the radiator. This sensor can look like the one here:

Hope this helps.

My 1990 ford f150 is smoking black exhaust what could be causing this?

Hello Warebaby.
Black exhaust indicates unburned fuel.
This can be caused by many things.
Bad ignition-spark plugs, wires, distributor cap, rotor, coil, ignition timing.
Excess fuel going in- bad injector, fuel pressure regulator.
Electronics-map sensor, throttle position sensor, oxygen sensor being most common.
Could be a good time to tune it up first
