I have been following this thread with interest as I just went through the installation of an R11 in my 38. I came up with my own wiring system which seems very simple. I ran a wire from the governor to a ON-OFF-MOMENTARY toggle switch under the dash then from the switch to the relay which only has 3 terminals (power in ,ground and switched power out). I then ran a wire from the distributor side of the coil to the momentary portion of the toggle switch so that the momentary position grounds through the gov. In operation the toggle is in the ON position and lifting off the gas allows shifting into OD. When I want to disengage the OD I flip the toggle to off and just blip the momentary and the car downshifts to regular. I never bothered to hook up an OD light because I know that as soon as I go over 20 MPH I can engage the OD. Also I didn't want to bother with installing a kickdown switch under the gas pedal.

--- momentary to coil

--- Gov (grnd when over 20 MPH)

--- Relay
