Amp wire - How I Did It
First - Find the gromet - Its located on the passager side just under the windscreen, about 3 inches from the edge of the inner wing - In the pic below you can not see the gromet but you can see the black silicon used to cover the hole the cable went through - I could only poke the gromet out so I made sure no water could get in to the car by filling with black silicon, its in a very dry place but its good not to take chances.

Removing air bag switch
You then need to take out the panel where the passager air bag switch is located - Pop the switch out,disconect it then remove the screw behind it.
Removing the panel
Follow the panel round- open up the glove box and remove the two screws holding it, You should now be able to remove the panel.
Finding the hole
Poke the end of your power wire in to the hole where the gromet was - Keep feeding it in and you should be able to see it through the removed Air bag switch panel you removed on the inside of the car.
I made a hook out of some wire and "hooked" the power cable, I then pulled it through.
Last steps
You can now take up passanger door trim and feed the cable to the boot
