I wanted to be able to mount my GPS on the ATV so I bought a waterproof 12v outlet from Wal-Mart for about
$8.00 and went to work.The outlet has two wires - one white and one grey. The grey one is the positive or + wire and is the one to add a fuse to if you're going to add a fuse.
This project was very simple. All you have to do is wire directly to the battery under the seat and mount the outlet on the right side of the ATV. I used to zip ties to mount the outlet to the frame. Here are the finished pics...
