Oh ok cool. I think I'm just going to run them from the front batt under the truck and into the bed to the back batts by just drilling holes into the floor of the bed. Then I'll run them from the back batts back into the cab through the cutout...there's a little room inbetween the box and cab.
Yeah, I know I'm slow, but I finally got the bracing in. Hopefully now I won't have to worry about the batteries breaking the box //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif The batteries fit pretty much perfectly. There is a tiny space between them that I'll probably use to put plexiglass in so that the + and - terminals cannot come into contact with one another.
Got 35 ft of power and ~40 ft of wire for ground. Hoping that I can get 8 powers and 8 grounds out of it. Also borrowed Snoopdan's drill press today and started on some aluminum distro blocks to go inside the battery box. Each block is an inch thick.
Both will be mounted inside the box on that back wall. The bolts are 2.5" long and will go through the box. My bed cover is on back order and is slowing the process down a little. Once it comes in then I'll get all the wiring ran.
