You will need a converter as has been mentioned. The wiring is simple if
you get those little crimpon doo dads (technical term) from the auto parts
store. They let you connect into existing wires without having to cut
them, buy pressing a small blade through the insulation and making the
connection that way. I bet there is a real term for them, but heck if I
can think of it :-)

Once you get the converter, its a snap to hook it up this way.

HTH,
