Come on over...this is a piece of cake! The hardest part will be getting into the clean out tray and reinstalling it. Send me a light to install, I will make you a video! Seriously, you need a switch, run wire to the switch, from switch to light, and a wire from ground to the light. Deciding where you want the switch, and the route through the boat to it is up to you. If it doest come with a fuse, it needs to be fused too. Remove all the panels to get access, drill the transom for the line and screw holes, bevel them (drilling in reverse) so they don't crack, pull your light cable through the center hole, use life caulk around the moat ring around the cable, in the 3 mounting holes you drilled, then place the fixture on the transom and have someone pull the cable through the hole from the back, install screws. Now go back up in the boat from behind and caulk liberally the screw holes and wire. Your done on the transom. Extend the wire to your switch and ground, and connect the switch to positive for power. Your done!
