It was time to start at a logical place running the power wires. The first task was to mount the fuse some 1/8 “ holes were drilled and some pop rivets were used. Next the battery ring terminal was crimped and soldered and the two ends of the wire that go into the fuse were tinned too. These were done inside too! There is a removable nut on the positive battery post to attach the positive to. It is good enough for a 40 amp max draw from the amp.
