[Fot] Rear End Ratios

Ed,
Your wiring sounds similar to what I used.  I used a commodity SPDT 
Bosch relay with the overdrive solenoid connected to the normally closed 
contact.  The switches were wired in parallel so that the overdrive 
works when all switches are off.

And you get this.... I just recently installed a J-type overdrive in my 
Model T boat tail speedster - very slick.  It goes about 55mph at 2000 
and I don't care to go much faster.
