It is fairly simple, actually. First install the new rubrail receiver, then holes have to be drilled through it and the hull both at the bow and at a stern sidewall location. The wire runs inside and behind the black rubrail insert. Use two strand #16 wire. The correct color code is gray, but you can use a red/black combo also. Cabela's sells this very reasonably in marine grade, by the foot.

The wire runs down the same side that has the stern light pole. From under the bow light, drill at an angle, or as you suggest, to access the rubrail. At the stern sidewall, about 1 foot forward of the transom and just inside the rubrail, drill though the hull. The hole is hidden by a terminal block (which can also be enclosed in a covering box) installed on the inside where the connections are made for both the bow light and the stern light pigtail disconnect. The switched power from the console runs into the hull tunnel (use Ancor two wire sheathed cable in the tunnel), out the back and into the battery box, and over to the ternimal block. See the Montauk album in my personal Website link for photos of the stern terminal block setup. The negative ground from the nav lights goes directly to the battery terminal and does not have to have a black wire running back up to the console.

Use #10 Ancor sheathed cable to bring house power up to the fuse block located under the console.

Use Cole Hersee M-476BP switch at the dash.
