CTEK sell male 12v plugs that allow the battery to be charged via the cigarette lighter socket. 

All the 12v sockets in my mk3 are ignition live but I have been thinking I’d like to be able to charge the battery via a socket in the boot.

I already have a CTEK connector plug near the battery in the engine bay, and connect to that, but as I reverse onto my drive that means running a lead along the full length of the car.

If I installed a perm live 12v cigarette socket or CTEK plug in the boot and connected it to the perm live towing loom could I use that to charge the battery?

 

CTEK plug kit.

Is the towing loom fitted to the ST220?  Maybe just the lighting side if fitted?

 

If the wiring is there then no issues, the estate has the wiring for the rear lighter socket

even if no socket is fitted and thats live all the time.

Yes, the loom is there. I’ve used the ignition live on the loom to add a 12v socket in the boot.

I figured that I could tap into the perm live on the towing loom to add a CTEK plug.

 

It could be useful for putting the battery on charge if I work on the car or clean the inside with the doors open.

I’ve settled into a routine of charging the battery every two weeks, but that’s still not as good as charging from daily driving.
