Mounting solutions on topper carpet interior for generator wiring?

Hi all,
I've got some dangling wiring that are connected to a deep cycle battery generator I installed adjacent to my truck bed drawer system and looking for clever ways to get this wiring out of the way. I've tried using industrial strength carpet tape and a few variations of that adhesive to seal it up on the interior topper carpet, but nothing's worked too well yet. Curious if anyone has any clever suggestions based on how they've mounted things in their interior topper?

(I currently don't have any hooks in the truck topper to zip tie anything to - trying to avoid drilling holes in new places until I exhaust all options) Thanks all

 

Velcro sticks nicely to carpet.
