Most of the one's I've seen are the plug in the cigar lighter style which doesn't work since MB's cigar lighter is turned off with the key. But if they have one designed to use under the hood it should work.

If you are just a little handy, get a battery connector for 9v (looks like a plastic piece with maie/female snaps and two wires, some wire and a couple of alligator clips. Solder it up, add a 9v battery and connect under the hood.
