just to let ya know you dont need a key or a key switch at all, i just removed mine for ease. the way i looked at it is if i had a key anyone with half a brain can just unplug it and be gone or aside from that if someone wants my blasty they could jsut pick it up and carry it away lol.
here ya go. i was nice enough to take my hood off for you.
see the 2 bolts? there are 2 more on the other side. remove those and take off the hood.
see those butt splices? you'll need to find both of those. if you don't have a key switch, look on ebay for a cheap one. it will plug into these splices.
