The 39 Deluxe and 39 Standard equipped with a radio both use the same voltage regulator and 2 brush generator, as opposed to the 39 Standard without a radio that uses a cutout and 3 brush generator. Would the 39 Deluxe and 39 Standard with radio both then use the same main wiring harness?

Russ, first and perhaps foremost, a '39 standard did not necessarily have a cut out if the car was equipped with a radio. That is a fallacy. In mid 1939 production, nearly all cars were equipped with a voltage regulator. That is, until the stock of cutouts was used up and / or returned for service part use. The same wire harness was used for all cars that came from the factory with a voltage regulator. Cars that were authentically equipped with a cutout but later changed over to a voltage regulator were fitted with a short "adapter" harness supplied by Ford.

Mike, Thanks for your reply. I was not asserting that 39 Standards equipped with a radio used a cutout, but rather that 39 Standards with factory radio used the 2 brush generator with voltage regulator (same as 39 Deluxe). This is my understanding from the 38-39 Ford Book. My question really is about obtaining the correct wiring harness for my Standard that is factory equipped with a radio. The usual vendors tend to market the main harness as either for a 39 Standard or 39 Deluxe, i.e. without making a radio distinction. My guess is that the harness marketed as 39 Deluxe will work with my 39 Standard equipped with radio. Looking for confirmation or contradiction of same. -Russ Russ H Southeast PA

Russ, I was only attempting to clarify the fact that standard cars had a voltage regulator direct from the assembly line on about half the cars built. Radio or not, about half had a voltage regulator. Cars that were built with a cutout but later converted to a regulator were fitted with an adapter harness to allow this modification. Somewhere around here I have a service letter that allowed the part number and an illustration as to where (how) that adapter harness was to be installed. I'd suggest you purchase a harness for the deluxe model. It will fit your standard model and be built for a regulator.
