Planning on doing the same thing for camp lighting/chase lights.
For S2 wiring ideas check out this post (Cable Routing - Exterior Lights) and this post (Show us your truck! - Herrmann552). Planning on going one of these routes and sending the wires to a fuse block/relay and put a switch in the cab.
I also really like how @zwickt, @bingbong, and @Vice_Chief setup their interior lighting and will be doing a variation of these.
