Sorry if this has been beaten like a dead horse, but I have searched around and didn't find what I was looking for. PO installed some flood lights onto the drivers side of the roof rack, and the wiring runs down the drivers side of the windshield and into a switch box mounted in the passenger side of the engine bay where the AHC stuff used to be. I have a light bar and I would like to run the wiring down the passenger side. PO has the wiring secured as pictured below. In examining it, I can't tell if it's just some 3M tape or something else, as it seems to hold its shape when I lift it off. It's sticky on one side, so I think it might just be as simple as that. Is there some sort of product that is used to wedge wiring into that gap? Some sort of press fit bent tab seems like it would work well. What's your favorite way of holding wiring in place in this location?
