can anyone tell me what do these plugs do?

 

The middle is the distributor sensors, the black one on the right is the coolant temperature sensor.

 

the black one on the right goes on the back of the block

1. DX style 6 pin distributor plug
2. Fan switch wires

Water Tempature sensor ("TW Sensor") is on the side of the engine under the distributor.
