Any ideas as to the best pickup point to connect constant power from the rear of the RRS HSE 2012 fitted with 13 pin electrics fitted already, but want to have power to run fridge in caravan when towing.

13 pin has a couple of pins for that already, doesn't it?

Found this via Google

yeah pin 10 by the look of it

This is what I based mine on.

You do not want constant power to your fridge as it will flatten the car battery when the engine is not running.

The fridge is normally connected through a relay in the car and only gets power when the engine is running.

If you have a tow kit fitted the relay should be there, it may have blown a fuse, don’t know about the Sport but my full fat had 3 fuses for the tow electrics one of which was in the front fuse box.

Ian 2018 Indus Silver SDV6 Autobiography normally towing a Buccaneer Cruiser.

My 2013 Sport has the 13 Pin electrics and the fridge and perm 12v both are wired and working.

I can't remember where the fuse is (IIRC it's in the bonnet fuse box) the old ones were in the boot. 2016 Black SDV8 Autobiography
2013 Grey Black Edition SDV6 (lasted a while but gone now)
2005 Grey Supercharged Sport (gone but never forgotten)

I think fuses 48 and 54 in the fuse box behind the glove box are for the ignition feed (Pin 10) and permanent battery supply (Pin 9) to rear tow socket. 54 is ignition and 48 permanent battery feed.
