1966 Ford F100 4X4 SWB Styleside 352 NP-435

The FoMoCo wiring diagrams I have show a 70 amp circuit breaker between the solenoid and ammeter.....can anyone show me where it physically mounts (inside fender wells? Under dash?), what does it look like? Will a c3Tz-14526-A be a part for this application, as I have one of the 70 amp breakers?

The PO apparently removed it.

Number Dummy, hope you are OK and can tell me if the above part will work.......or where one is that will.

Thanks in advance, ND the truck is now being wired and body fitted.....to final fit and finish soon.......will share with all when I get a little closer......thanks, m.
