Hi
New to the forum and require some help.
Car in question is a TA Antarctica.
I've fitted a tow bar and wired up all the back end.
Does anyone know if there is a spare space in the fuse box to take the power from?
If so which fuse no.?
Thanks in advance.

I don't think there is.
The dedicated wiring kit that's available has it's own fuse, fuse holder and wiring to the battery, so I reckon there isn't a spare in the fuse box otherwise they'd have utilised it.

You can wire into the fusebox. Thats how mine is done.. Saves all the hassle of getting a cable through into the engine bay.

page 9 of this may help??

BTW, my wiring kit is the westfalia one, but we ignored the instructions to connect to the battery and connected inside the car instead.
