Just for future posts you dont have to say 3rd gen and FD, either one will let most people know what you are talking about.
on the discharge of the water pump there is a single wire (black) going to a sensor right before the radiator hose. This is the level pickup.
It isnt a float level or anything like that, it works off resistance to ground. If you want to check the system, you can apply ground to this wire and within 30secs it should stop if the sensor is bad.
