When it came time to run the cables on my truck I was kind of stuck. I couldn't run the cables under the frame due to the suspension. If I went over the frame it was close to the box sides and it didn't lay out very well. My friend suggested we go through the frame. I got a piece of 3/4 inch gas pipe out of the dumpster at work and we went to work. An hour and a half later it was done and I think it turned out pretty nice.
