This switch is also used for the overdrive to ensure engagement only in 3/4

Hi Frank,
How's it feel to be a civvy again?
The switch you are refering to is for the Shift Activated Advance
Solenoid (I can't recall the propper name). It is activated in 4th gear
and the solenoid is attached to the top cover of the master cylinder
mount. Vacuum hoses attach to it from the manifold and dizzy. It causes
full vacuum advance in 4th only.
