I did exactly that when I had my Tempo Electric SCs. It was recommended by the owner who said to run the cable through the hole of the bottom post and up through the top one in the same fashion. He even supplied me with some tubing that I cut to size and slice lengthwise to cover the bare wire. It sounded great but not really better than using jumpers.
It was very difficult to work with since the wire was solid, 14 GA silver and the posts weren’t lined up directly (line of sight). Both sets of posts were on a different step of a stepped layer and the wire had to be painstakingly threaded, bent, pushed, bent, and so on to guide it over and upwards. A real PITA. I hope yours are more directly in line of sight to each other.
All the best,
