Here is an update on the battery move so far... been working kind of slow, working little bit each day.
I removed entire ground wire going from battery to engine and chassis and also the power wire going from battery to starter and main fuse.
Wire going from distribution block to fuse.
Wire going from Distribution box to starter motor
Distribution box
The wires all tired up together ready to be covered with electrical tape to clean it all up
The main power wire in the wire conduit, running along the frame rail.
Hole where the wire comes through the floor and also the battery box mounted securely to the floor.
