Hey PAMELA MCDONALD,

Please see the attached instructions for PCM replacement on your vehicle.

Also the location of the PCM if you are unsure.

Hope that gives you what you need.

You will need to program the new PCM to the vehicle, sometimes the vehicle will not start without programming after PCM replacement so you will need access to a scanner with this function or undo the unit so the new unit can be easily plugged in for a Pontiac dealer to program. Then you will not get charged for the installation just the program.

Don't hesitate if you need any further information.

Regards, Joe
