Helpful Expert Reply:
To install a 7-way connector on your GMC W3500 to fit the 7-way connector you referenced in your picture you will first need to install a 4-pole wiring harness such as the Upgraded Heavy Duty ModuLite Circuit Protected Vehicle Wiring Harness # C59496 on your vehicle.
In addition you will need the etrailer Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat # ETBC7 which will convert your 4-pole connector to a 7-way and 4-pole connector.
If you can give me the year of your vehicle I can check to see if we offer a custom fit 4-pole vehicle harness that will allow for plug and play installation instead of splicing into your vehicles harness.
