Key on these old Fords is to fuse, in some way, at the source. Falcons, and other early cars, had nothing between the battery and some small assortment of fuses. By the 65 model there was a small fuse block, but prior to that only a couple circuits were fused... and the fuses were on the headlight switch! When I rewire I make sure any wire, of any size, gets a fuse starting at the starter solenoid. You can start big there and go downward in size in the interior. I put a 3-fuse block on Jeff's wagon and broke-out the headlight fuses.

Reminds me, I need to update his build thread...
