Hello Mark, thanks for reaching out. We do have wiring options for the 2002 GMC Sierra. What we have is designed to replace the factory 7-way and will plug in to the standard USCAR connector (pictured below). As long as this is what you have, you can use the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket # HM40975.

Hey Mark, how did the 7- and 4-way connector work out on your Sierra? Knowing if it plugged into your factory block cleanly could help others sorting through the same wiring setup. Your update could make it easier for the next person with this truck.
