Did you get your wiring done yet?
I ran my HAM radio wires through the same place, I cut a slit and RTV'd it closed though.Batteries are in the KK and wired. Next will be the aux tank...waiting for another couple connectors from Japan...hopefully here later this week.
I have the drawers and trim pieces out of the LC. I found where all the dust has been getting into the rear of my LC: Looks like when I had the trailer wiring and/or the Prodigy installed and wired they pulled the rear lower fender body caps...ran the wire through the holes (one on each fender)...and left it open . You can imagine how much dust gets sucked into the rig with a couple of exposed 2" holes!
But glad I found the cause! Now maybe I won't have to carry around so much Kleenex
