Access to the rear of the whole dashboard in one of the easier jobs on a Morgan.
First drop down the steering column to its lowest setting
Then take out the two wood screws, one each side of the dashboard at the lower corners.
The whole dashboard will then come towards you in the car. Most of what lies behind is now accessible.
Only a few tips , try not to leave the dash supported only by electrical cables or you risk later connection problems, give the earths a good tighten up while you are in there, lastly label the relays which are mounted on the wooden bulkhead (it will save you lots of time later) Sorry I can't remember offhand which is which but there are 4 in total (unless someone has added additional items post delivery)
This should give you all the access you need to the back of the glovebox.
That socket was designed (and fused?) for a trickle charger, if you are planning to run any high current items you might need to think about the fuse value.
