I bought a 12v socket from
Ultimate Mobiles with the intention of placing it in my top box - for charging netbook, camera and so on, while on the move.
The cable, at one metre long, would be just long enough for the distance from my Tenere top box to battery, but i'd need to unbolt it from the battery to take the top box off.
Therefore, I cut the cable and lengthened it will the addition of a pair of connectors from maplin (
here and
here)
I decided on drilling a hole in the bottom of the box, but not the mounting plate/rack and instead fed it behind then under the seat.
A few pictures:
Under the seat, with the connector hanging out to the right:
Inside the topbox before tidying up:
And the only visible bit after completion:
