Coolant temp sensor should be inside the thermostat housing. Follow your upper radiator hose to the housing and look for the plug on it. That would be your ECT sensor (IDK, it might be hidden on those though. This is a general comment.)

As for your "Side rails"... what do you mean side rails? Step bars or bed rails?

Your model does not have a coolant temp sensor, but infers the coolant temp from the cylinder head temp sensor.
