I think it is easiest to take the power straight from the bulkhead connector like this. https://www.67-72chevytrucks.com/vbo...d.php?t=708975

Fuse is not necessary but if you would like to add one inline anyway it should work fine with a 10 amp fuse. I find my HEI takes 2 amps of current to run.

I suggest now is an opportunity to check that you have a fusible link wire at the battery to protect the smallest gauge unfused wiring in your truck. In a truck wired like stock the unfused wiring before the fuse panel is 12 gauge, so you would use 6 to 9 inches of 16 gauge fusible link wire to connect the 12 gauge red wire to the battery.
