A pig tail for a coolant probe is a short wiring harness that connects the coolant probe to the vehicle’s electrical system. It typically consists of two or three wires, depending on the type of coolant probe, and a connector on each end. The connector at the vehicle end is typically a standard electrical connector that is compatible with the vehicle’s wiring harness.
Pig tails for coolant probes are used in a variety of applications, including:
- Engine coolant temperature sensors
- Coolant level sensors
- Coolant flow sensors
- Radiator fan switches
Pig tails are often used to replace damaged or corroded wiring harnesses.
