I believe what the OP was seeing was a dealership prep job done by a kid; wrong color, not cut, crappy prep.
I have like others here cut myself too many times from careless install of cable ties/zip ties from other's sloppy workmanship. If they're tensioned too tight, especially on wiring harnesses on most machinery, tractors, boats, cars, what have you, they can cause wiring issues over time.
I read recently a manufacturer of joystick handles for tractors/excavators, etc. stating NOT to use them in certain instances where wire harnesses bend sharply etc, and if used at all to make sure that they were not crushing or straining the wires below the sheath, etc.
That got me to thinking. I have replaced hundreds of ties on my boat as I work through the rat's nest of original and two owner's prior to me attempts to fix or rearrange wiring. What I started and continue to use is narrow Velcro ties that come on a roll, available at home centers. The one I use most has one roll of gray and one of black. I find this allows me to rebundle existing or new wiring and gives me access later without having to cut and replace a zip tie. AND it allows for safer rebundling because by not cutting any ties except for what is already in place there is way less chance of accidentally cutting a wire or nicking it. AND I can put a couple of ties together one after another to wrap much larger bundles or go around a ROPS, for instance, or a marine grade T top tube for cleaning the metal as needed, without having to hide the zip tie block, etc. And they're reusable- not something a zip tie can claim.
Give it a try- It's been working for me and for a number of years of 'in house' testing shows they are easy to use and get done what I need to without having to cut and replace over and over.:thumbsup:
