Now onto the positive side. I did the same as the negative but this time i joined both the left and right wiring into one so only one wire had to go down into the car. I extended the main wire from the left light over to the right and soldered them together there.
To actually power the lights, lots of people have used the number plate lights. If you remove the carpet on the drivers side boot, you should see a big rubber grommet with a wire passing through. That should be your number plate loom. My wires were brown and brown / white. I used a multi-metre to work out which one was giving power, stripped it and soldered my own wire onto it.
