30-something year old wiring and connectors isn't quite as sprightly as it used to be.
First and foremost, the connector on the coolant level sensor is damaged and previous repairs have failed. It needs replacement connectors and a new plug housing.
The connections to the coolant sensor and pump are ok, but the plug housings could also be freshened up with new ones.
The coolant level and washer level connections use the black straight housing 61-13-1-378-408, the pump uses a grey 90° plug. Note: There are several 90° housings and each is differently keyed, it appears the grey one is appropriate here.
