First of all I purchased some stainless replacement cup holders for all my plastice ones. I drilled a small hole for the two 20ga wires then laid the tape on the wall of the larger diameter of the cup holder. The normal aluminum can will fit down in the small diameter, i suppose the larger diameter is for the can coozie but have not had any trouble.
When I get the boat out of storage I will post better photos. I did all the cup holders, gunwells, under the back seat, under the dash and the pocket by the throttle. Also purchased two LED speaker rings for the two exposed speakers in the bow.
I was testing everything with a 9v battery when I was wiring it all up then hit the 12v switch and it is very bright! Now I need to wear my cheap sunglasses at night!
