No - Don't do it!! Wire up a socket direct to the battery with an inline fuse -- you can buy these in Halfrauds or the like. All that is needed is a small hole in the wooden bulkhead to get the wires through to the battery.
The lighter socket in the glovebox is on a fuse with the lights and something else I can't remember and this WILL blow on a charger(I did it on my 2009 Plus4 before I copped on!!) which then leaves you without lights and no charging either!!
Make sure you use a charger which handles the glass mat batteries
Cheers!
