Where do I find the wire for my cruise control?
The installation manual should provide you with the correct wire colors and location, if not click here or on the link at the bottom of this page. Most all vehicles today have what is known as a VSS ( Vehicle Speed Signal ) wire. This wire provides the signal the cruise control will monitor to maintain a constant speed.
What does the coast signal on a cruise control mean?
Cruise Set/Coast Signal – This is a momentary switch signal which sends 12v+ down this wire. Momentary meaning, it only sends 12v+ when the switch is pressed, when you release the switch, it should turn off. Pressing this switch quickly will set the current speed and it will be maintained.
What are the cruise control switches on a GM car?
Cruise Control Switches: The required cruise control switch signals multifunction lever of GM steering columns. The on/off signal is normally open switched 12V, the set/ coast signal is momentary 12V, and the resume/accel signal is momentary 12V.
How does the cruise control monitor the speed?
This wire provides the signal the cruise control will monitor to maintain a constant speed. But for those that do not have a VSS wire, including older vehicles, a signal generator or a pick up coil and magnets can be added to monitor the vehicle’s speed.

Which is cruise control signal does the PCM output?
PCM: In production vehicles, the PCM is used to output a 4,000-pulseper- mile VSS signal to the cruise control module. This is a common pulse count used with many early GM ECMs and VSS buffer boxes. An optional cruise engaged status signal is available for communication between the PCM and cruise control module.
