I took the easy way out...

I just got a cig socket double adaptor - one with the two sockets on short wires - and put it in the socket in the centre console. I then ran a cig plug lead out through a small hole I made in the back of the console and plugged it in too one of the two sockets. It is connected to a fuse block which runs the UHF, six tyre TPMS, phone charger, 7" Samsung tablet I run OziExplorer on, etc.

I still have a socket available in the console.
