I posted this elsewhere recently.--It's very easy and quick to do.

Now go get that battery and jump leads and do it.---

Thanks Jon for that.
I have a thirteen pin socket which I assume is a Euro socket. Pin 9 should be live and pin 13 ground. I was worried the current from another battery might exceed the fuse rating on the circuit if the battery in the car is very flat. It will be great if it works. I guess I could put a 10a in - line fuse as a precaution. I shall give it a try tomorrow and report back
