lol well its got 2 wires 1 has a eyelet for the earth then the other needs to be joined and run to the switch then it goes thru a fuse supply (handy speaker wire in a estate version runs right from front to rear)

otherwise all you need to do is mount it suitably and connect it with a rod of some kind

in my estate i just bent the original (from the lock) thru the popper and pop riveted it onto the inner skin


can also put a 2nd switch in to be a secret way in if you lose keys or summet

i wals always losin estate keys so i had a snd button no steerin lock and the lower cowel only on by 1 screw so it was easy for me to get home ans use it till they turned up again
