Is the frame prepped for internal cabling? If not how are you going to make the provisions to run the cabling in the tubes? I cannot tell from the picture, the frame may well have the inlets and outlets for the cables installed. Not a flame or calling you out, I'd just like to know if you could do the work for internal cables. Cutting and drilling and brazing or epoxying in the fittings (the frame appears to be aluminum to me) would be pretty extensive. Best of luck with the conversion, regardless.
