1947 Ford car cowl harness differences

[Kurt in NJ]

I think it is the location of the ballast resistor, later cars had it on the coil, 46 was inside next to circuit breaker---at least it was that way on the 48 i parted for my 46---as for other differences I don't know---well the 48 just had ignition switch like later car, 46 had steering lock
