Kw t-800 batt to cb cabinet power

I need to get a new bigger set of power wires from my battery case on a Kenworth T-800 to the pull out overhead CB rack. Has anyone ever done this? I was looking the truck over this AM for a solution...I see a LOT of screwed on plastic, and the wires that are currently up there in the cabinet come from the fuse panel, not the batterry, so I can't just use them to pull a new set. I hate to have exposed wiring in the truck laying around on the dash.

Thanks In Advance

 

I need to get to the battery to reduce RF interference, but if you have experience hiding the wires to the fuse panel, I really would like to hear about that! It's a 2006 KW T-800 with the electronic dash...lots of plastic covers and overhead cb sliding shelf.
Thanks In Advance

 

no, it's a 2 pice windshield, but I don't think I can get the wire size I need in the center support without causing a seal prob with the windshield...I looked at that

 

What do you mean by eyebrow part? I don't think I can use the light guage wires for pulling because they are tied together with other wiring in the top shelf/cabinet area of the truck on close examination
