Sorry dude more questions
. Is the new ariel electric as well? If so its just a matter of unplugging the old ariel and plugging in the new one - you need carefully to follow the cable from inside the car through to the wing so you know how the new one fits in. They are all a standard cable size as far as I know - the electric ones are a little more complicated in that they have a few more wires but its again a matter of following the cables back to see where thay plug in.
I always disconnect the battery when cabling things up as it is so easy to trip a fuse.
