Helpful Expert Reply:
You will want the OEM Style 7-Way and 4-Way Trailer Connector, # HM40975, which will allow the use of 7-Way and 4-Way wiring with no additional adapters. You will need to make a few more connections under the hood of your 2007 GMC Sierra Classic to complete the install.
See the FAQ page I attached for how this is done.
