Clean Rack Light Install Options

Getting close to running wires for the lights on the rack. What are others using to keep it neat and clean?
I though of getting some split loom and loom fittings. Running it between the cab and the cap. But the plastic loom looks cheap and I question if it will hold up over time.

Also though of using mesh loom or snakeskin. I don't think they make fittings so I question the ability of having a clean install.

Any recommendations and or suggestion are greatly appreciated. I only want to do this once.

 

I have not done my wiring yet. It I was going to go with cloth loom. For "fittings" I was going to use marine grade shrink tube

 

Didn't think I'd shrink tube. That's an idea. How are you running from the rack down?

 

I'm thinking about drilling out a hole in the corner of the bed guard. I'm going with an aluminum rack so I may run the wires inside the rack bars but again I haven't fully decided yet

 

With a rack, that would be a clean out of sight install. I thought about drilling a hole in the topper and running my wires down through there. But don't want to worry about leaking in the future.
