You may remember my post before about the berlingo cigarette lighter.
Ive' got a 1999 berlingo multispace, the lighter is wired through the ignition system. Therefore, it won't work without the key being in. The best way around it that I can think of is to fit an auxillary socket in the back of the car.
Can anybody recommend which guage of wiring to use, and what size fuse. I don't want to start a fire!
