Adding another accessory socket in boot area

[patch]

Always nice to know there is more than one way to do something and the pro's and con's to bear in mind.

Once work done the next issue is going to be where to site the damn camera. The back window has aftermarket tinting so I think sticking the whole thing on the window could cause a problem with the adhered film. I.e the camera is stuck to a thing light film not the window itself
