This page shows the modification you'll have to make to the cruise control stalk. This shows how to modify the single button cruise control/turn signal stalk that was common to many GM cars in the mid to late 70's. The cruise control stalk of these years just have a single button in the end of the housing and is marked by the word "cruise".  Yours may be different depending on the model of car you're installing this in, and whether you can find and modify a similar part.

The first thing is to locate the switch housing to be modified. The one 's I found were used in many mid 70's to very early 80's Cadillac's.  

   

   

  

                                     

The first picture is the Cadillac cruise arm. The parts you are going to use from it are the cruise switch housing, button, retaining ring, switch cover and switch slider. Throw the 3 wire harness and arm away.

The second picture is the cruise arm found on many late 80's to early 90's FWD GM's such as Grand Am's, Grand Prix's etc. The parts you'll use from it are switch and  wiring. First we'll get the parts from the late model switch.

Put the switch is a vise and remove the cover as in the photo. 

 

Pry the end button and remove the switch slider.

Pry out the "star" retaining ring that holds the switch in place.

Use a small screwdriver in the switch slot where the slider use to be, push on switch to pull it out of the housing.  

 

Before you cut the wires, scribe the wire colors to match each switch terminal. Once you have done this, cut the wires and pull the wire harness out of  the stalk. You'll need the switch and the wire harness. Discard the rest of pieces.

Do the same thing with the Cadillac cruise arm, except you'll keep the cruise switch housing, switch slider and switch cover, button and the retaining ring.

Pull the cruise housing end off carefully.

With the original cruise stalk from your vehicle or one from a salvage yard, take the 4 wire cruise harness, twist the wires together to get it small enough and push it through the right hand end and pull the wire through as shown above.
