Hi I need some advice, my H33 does not have any wires / power leading to the steel arch and I want to add 12v overhead, so I am thinking to use a drill to make a hole in portside locker in the middle of tube and then rod a cable up to another new hole in the same tube at the top somewhere. My question is has anyone else ever added power or routed a cable using this method or do they know if one of the tubes has a designated hole already in place to add a cable? I mean to add a light overhead or a speaker.
