Looking for insight on running cables through the headliner from the compression post to the electrical panel. There is a cable tunnel molded into the headliner to join these two locations but the cables keep getting hung up in the tunnel. From the cabin this tunnel looks plenty large enough to accommodate all of the cables but there are two bends that seem to pinch points especially when trying to pull the large VHF cable, and the radar data cable that has a connector on the end. I am almost ready to cut a hole in the center of the tunnel to have an intermediate pulling point, and then cover it with an inspection plate when we finish. Any other suggestions?
