Pontiac G5 2007 fuse box diagram Auto Genius

This car has electric steering, you must have the system checked by the dealer.

THE DEALER WOULD HAVE TO PROGRAM THE BODY CONTROL MODULE TO RECOGNIZE THE ADDED CRUISE CONTROL.

you will require a new steering wheel.
and it is almost $500 from the dealer.
It will look like this...


The aftermarket one does not stick off the handgrips of the steering wheel - it is on the bottom Hub area.


The aftermarket uses a wireless transponder and the brain is hard-wired into the ECU (computer)

Im not sure that your vehicle has the existing wires in the harness to facilitate adding a cruise in the steering wheel without replacing the entire steering column... or wiring harness.

Im sure with the right amount of $$ it can be done - but the aftermarket one is the least invasive and cheapest route for you.

All the cars... cobalt, g5, g6, g7 etc... have the cruise control built in the ECU, and it simply needs to be turned on using the GM Tech Tool Candi II. Its the part about switching it on and off that the costs are involved.

Go with the aftermarket - its really not that bad!
