What's required to enable factory cruise in an '07 Silverado that wasn't originally equipped? Checkboxes in PCM programming? BCM Reprogramming? Anything else?

2007 Classic (PCM) or 2007 new body style (E38)?
New body.
The OEM cruise switch is a 3 resistor setup ... cruise control signals are sent to the BCM ... then CAN Bus comms to the ECM.
You will need an OEM switch (or equivalent) ... one side to switched power, the other side to the BCM.
As far as programming goes ... the ECM is ready to go ... some BCMs work without additional programming. Sometimes the cruise will function, but the indicator on the dash won't illuminate. Sometimes the BCM won't allow the cruise to function at all.
You won't know what level of functionality you will have until you try it.
Older systems tend to be more user friendly.
Thank you.
