Blue/green blue 2 way connector behind battery
 

After changing the battery on my x type I noticed a two wire connector with blue/green and blue wire which was not connected to anything. Thought it might be the connector for a water coolant level sensor but but doesn't seem to fit into the bottom of the water coolant expansion tank. No warning lights on dash. If it doesn't go to the water level sensor where does it go ? Do I need to worry about it or is it redundant wiring.

I think you'll find it is a transit connection for the battery used during initial delivery.
There should be a dummy connection on the battery box for it to clip into.

Thanks Norrie. This is my first experience of the Jaguar Forum and I must say it's great to be able to communicate with people who are interested and knowledgable about Jaguar cars:D
