There's really no reason to move the battery unless getting tubs.
Had some time to snap pics. I got the foam idea from scotty-2-forty's build thread on nico. Turned out pretty good IMO. The battery is solid to the floor and is not going anywhere. The 200amp ANL fuse is on a bracket just behind the box. I also moved any existing wires away from the power wire to help prevent any unwanted noise in the system.
Had to make the hole bigger and trim the interior pieces where the wire is coming through above the wheel well. Would have been easier to just run it above the shock tower but oh well... less length this way. The cable runs along the bottom of the trans tunnel to the firewall.
Still need to put conduit on the engine bay side. I just crammed the 3 old power wires into a lug, soldered it closed and connected that to the new power wire as a temporary solution. I'll probably run it to the starter or put the fuse box in the glove box when I swap engines and tuck what I can. Ended up using a section of heater hose as a firewall grommet since I couldn't find any actual grommets that would fit right (needs to have a 10mm+ groove which is hard to find). I'll eventually get a proper grommet for aesthetic reasons.
What the cables look like after hammer crimp and solder.
