How To Install 7/4-Way Trailer Connector On 2021 Chevy Silverado 1500


I have a new 2021 Silverado with no receiver hitch so I am ordering the Curt 13393 hitch and I need a plug and play 7/4 way wiring harness for trailering. Please let me know witch harness I need, not for 5th wheel or goose neck, regular bumper hitch only. Thank you.


Expert Reply:

The 2021 Chevrolet Silverado 1500 comes pre-wired for a trailer connector and there is a knockout panel already in the bumper so all you need to get up and running is the 7- and 4-Pole Trailer Connector Socket part # HM40975. The included metal bracket can be discarded.
