Taming the snarl
I’m about to make your life easier.
The easiest and most effective way to bundle cables is by using spiral wrap. You can find it cheap at your local auto parts store. Cut it into two-inch lengths and put a length about every foot or so.
It’s reusable like velcro straps and twist ties, more adaptable than cable ties.
The best way I’ve found to route the bundled cable is stick-on cup hooks in alternate directions. Right left, right left, and so on.
