I'd like to buy a Sub-Troll 900 before I head over to Lake Michigan this summer for salmon. I have a 2 yo Lund Pro V 1775 which has a fuse box with several "accessory" slots, which I imagine means I could add the Sub-Troll. I am a little hesitant to start taking the console apart to get at the back side of the fuse box (which is on the side of the drivers side console) Hate to louse up such a nice electronic system but also want to get this done sooner than the local boat dealer can wire it for me. Any comments?
