sensor identification on 103.983 motor


I have attached an image of the rear top part of the motor on my 88 300E. I am trying to identify these sensors below the blue lines I have drawn on the image. I believe the sensor on the far right is the coolant temp sensor. I have circled one of the connectors as someone looks to have soldered the wire to the connector rather poorly and I believe that it may be causing the sensor to work improperly (poor gas mileage). I assume the replacement sensor does not come with the connector so I would probably have to buy a new connector and splice it in???

Can anyone tell me which sensor is which?
