I recently acquired a 93 d150 5.2l (cheap). It has a lot of problems, so this will be the first of many pleas for help. At this point I'm struggling with the two coolant temp sensors. One has 2 wires and the other has only 1. I just need to replace them, but when ordering parts I can only find one of the sensors. Maybe one is referred to by another name?

 

1. Coolant Temp Sensor
2. Coolant Temperature Sender for the gauge or light
