Wiring Rear cigarette sockets to Aux battery

[FMJ]

Hi,

I have a 2012 Multi with a Aux Battery fitted and would like to connect the two rear Cigarette lighter to sockets to exclusively run from the Aux battery which is under the front passenger seat. I vaguely recollect seeing instructions somewhere but cant find them, can anyone point me in the right direction? Is it as simple as removing the fuses for these and connecting the Aux battery to the fuse holder?

Thanks
