friends don't let friends so LED squirters....
if you insist on doing them, go to radio shack pick up some 18 gauge wire, a little toggle switch(prefereably with male spade connectors), a small barrel fuse holder and some female spade connectors. Put the squirters
in then run the hot wire(usually red) run that to the fuse, then to the hot side of the battery(don't put the fuse in yet). Run the ground wire into the cabin(usually through an existing grommet) and run it relatively close to where you want your switch, Mount your switch in a knockout panel, take a wire and run it to chassis ground(usually a nice screw into the subframe) then put a spade connector on the other end and plug that to the switch, and take the wire from your squirter
and put a spade connector on that bad boy, plug it into the other end of the switch, snap the switch back in, go put a fuse in then flip the switch and look at your squirters
