Beltfed, agreed. I guess to clarify my question, given the 3 items I am adding to the truck in OP, how many circuits will be necessary. I know headlamps, fogs, horn, turn, tail, wipers, hazzards, stereo, dash will need to be fused. What I am trying to accomplish is to place a fuse panel in an original component so as not to detract from the original look. But finding modern fuse panels that fit the size are a challenge. I plan to fuse the radio by itself.
I am attempting to glean what has to or should be fused through a panel and what can be fused through individual fusible links or add a fuses....
