Okay, there were only TWO versions of the Ford wiring harness. One for 6-cyl cars and one for 8-cyl cars. And they were all the same (identical). The terminal blocks used in the '50's Fords are really "junction-blocks" and the ones under the dash don't mount anywhere, they just hang inline. There is a third junction block near the front of the drivers side fender apron under the hood for headlight/parking light wiring. There are no breakers. All overcurrent protection are inline fuses except for the one on the back of the headlight switch for interior light circuit.
Ford had "accessory" wire harnesses for things like electric clock, radio, power seat, power windows, etc that simply plugged into the "Base wiring harness". If a car didn't have those options, the accessory harness (or individual wire) was omitted.
