Thanks so much for the helpful responses.
Let me rephrase my question since im still a bit unclear.
According to Borg Warner;
"In some applications before 1951, a reverse lockout switch was located between the kickdown switch and the governor. The reverse lockout switches were discontinued sometime during the 1950 model year and can be eliminated in prior year applications. No replacements are available. The wiring connections will be the same as explained above."
Their wiring diagrams show a manual switch to replace the early style transmission mounted reverse lockout switch. Is that the way the 51- and later systems all worked?
What has caused this confusion for me is a 1957 Chevrolet manual never mentioned this switch, just shove her down into overdrive and go ....basically.
That had me thinking Chevrolet wired it so the governor will always energize the solenoid in both freewheel and direct drive without a manual switch to prevent it.
I guess the author of that 1957 manual was thinking of the pre-1950 models?
Mr. Jackson, who built it for me said never tow in freewheel, so the cable is definitely needed for my application.
It's worked great for 13 years so far wired wrong, but after driving my '50 Studebaker working as Borg Warner designed it, I'm motivated to incorporate the relay and governor unit, but don't have much use for a working kickdown switch. I'm old and in no hurry to get places anyway.
