This is a replacement wiring loom plug complete with new terminals etc, 

This is the Plug that goes onto the Blue ECU Water Temp Sensor

This sensor is on the later model GQ TD42 engines after August 1995 and all GU TD42 engines.

This sensor is for the temp of the engine to tell the glow plugs when to stop glowing on Diesel Engines, and on Petrol engines is gives the temperature to the ECU.

It is common for this plug to have the wiring pulled out of it, it gets broken when being unplugged, and they deteriorate from Heat and then get a poor connection or sometimes the clip is broken, and they won't stay plugged in.

This can cause various running faults

Please check the plug, as earlier GQ TD42 engines have a different plug and run a different sensor.
