12v on dash

I have a VWT6 campervan camperking conversion that has leisure batteries in the back that run off the solar panel on the roof etc. There's is a 12v socket in the back that I use a lot for various things and that uses the the leisure battery but does anyone know if the 12v socket on the dash will run off the leisure battery or the main battery? Thanks
 
Got a pic? Would like to see the position so we can comment as could be original or aftermarket
