There is one at the front on the drivers side. Pull back the carpet in the footwell at the side nearest the door. You will see a small hole heading towards the fuse box. Poke your wire through with a long thin screwdriver. It goes to a nice gap in the engine bay.
So you dont have wires all around the outside of the car there is also a hole in the boot. Lift the carpet up on the petrol tank side. Again you will see a very small hole. Poke wire through with long screwdriver
