from my memory, that last picture with the green single wire sensor/connector is the ep91 fan switch i believe---it sits on the thermostat housing and points to the firewall
the coolant temperate sensor is a 3 wire connector and gray sensor with a triangular shape that sits under the distributor in the water housing,,,if i remember correctly...i think this one sends a signal to the ecu/cluster
hopefully some one else can verify, i'm certainly not into electronics
