The adapter lead will only work if it is a ctek 5.0 charger I think. It is available on amazon. I goes from battery outside the bonnet and is permanently attached to battery terminals and is a little plug that I leave sitting on the area just below windscreen outside the bonnet. It is not obtrusive .I can recommend this ctek 5.0 charger available on amazon so search for the attachment which is cheap and also the charger
