	Just a quick double check that I've remembered correctly. Extra accessory socket wired as normal (+ to +, - to -), then make sure the socket is completely insulated from the car body. I will be adding an inline fuse and maybe a relay depending on if the customer wants to be able to switch the charger off. Car is a 1952 Jowett Jupiter.

	Pretty much, yeah. There is a "proper" way of doing it which involves an isolation transformer and all sorts of pisballing around, but just an insulated socket wired up with positive to the centre pin and a fuse in the negative wire (or both) will be fine really.
