was doing some modifications on my 1999 2859 ciera express. found one red and one black 2/0 power cables tucked behind the blower tubes on the port side of the engine compartment. curious, I crawled around a bit trying to see what they went to. they follow the transom and dissapear under the cabin on the starboard side. I removed several panels and still cant find the other end. does anyone know what they are or what they used to go to?
