Been working on the battery relocation. Based on battery size, the only place I can put it without interfering with the cargo access panels & carrying large sheets of plywood, etc., is the left rear. I bought the hydraulic crimp tool for the larger connectors. The hold-down rods pass through a tie plate under the access panel, that is bolted to the base of the rear well. Access panel is also bolted to the inner rail, through the battery box. Makes it a bit of a PITA to remove, but this way I know it's' about as safe as can be. The vent tube is located in the corner of the box, and passes down & out through the fender vent panel. Battery ground & fuse block Cable runs alongside conduit under rear seat back from cargo area, then into conduit. I was able to fit the cable through the firewall pass through into the bay, even with all the existing add ons I have in place. Used another fuse block as a junction - other side (rear) is the existing feed to the starter. Battery ground is now secured to the frame rail, along with a ground to the transmission case.
