Hmmm, that is a great question. The first time was 2 years ago. If I did cut the zip tie I did not put it back on. If I recall correctly, the extra wires were folded over and tucked into the backbone on top of the length coming back. It was cold both times I did mine and I could not get them back into the backbone so I just tucked it in front of the rear fender, going down. I am not sure if there is more than one harness visible in the back but it is a fair sized harness. This is starting to make me think I should take pictures of future mods for reference. On that note, I should have step by step pictures on a cam install in a few weeks!
