I have a 1967 442 and on the turn signal stalk ther is a black button on the end. Oldsmobility said it's for cruise control. Can someone please tell what it is? Thanks.

 

Maybe, post a pic. Cruise stalks varied quite a bit over the year. The button on most cruise stalks is the 'set point' signal to the transducer to hold that vacuum setting.

 

It was for the rudimentary cruise control.

 

Does the stalk look like this (from 67 Cutlass Assembly Manual)? Eric, never asked you if your 67 had cruise?

 

No mine doesn't, I believe they are pretty rare for the 60's in general. Plus I'm old school I like to operate the fun pedal. I think in the last 25 years, I don't think I've used cruise 25 times.

 

Desperado, can you find evidence of cruise control hardware in the engine compartment? There should also be a dash switch somewhere (likely on the left side of steering colum) to turn cruise on/off

 

'68 and earlier Cutlass did not have off/on switch.

 

You mean it was always on? That just sounds wrong.

 

It's only on when you push the button. I always have thought that is redundant. Like having a separate on/off switch on the wall to turn on, so the regular light switch on the wall will turn on a light.

 

So how does it turn off? Does it disengage with brake application? Sounds like a confusing system.

 

It is extremely high tech. Push button 'ON' Step on brake 'OFF'

 

Wow, high tech it is! "On" then not only turns the unit on but creates the set point signal for vacuum. That would be enough to confuse most blondes I know. ON/OFF. Why would anyone want something more complicated??? Why that's almost as bad as trying to explain the need for 710.

 

The system does not have a speed compensator or any way to increase or decrease speed electrically. It was a basic vacuum actuated throttle positioning locking mechanism. Like I said very rudimentary system compared to todays. I remember when you could buy a similar aftermarket basic cruise control from anywhere.
