The broader product description calls it a custom wiring connector while the title and features describe a T-connector harness, and dust-cover inclusion is stated in the description and manufacturer content but is not confirmed in the explicit included-components entry.

Customer feedback reports positive impressions of fit and product quality. That feedback may matter to buyers prioritizing a vehicle-specific plug-in connection, but it does not establish fitment for a particular Traverse year or independently verify the harness specifications. Ratings are mostly five-star, with a smaller spread across lower star categories, so experiences are not uniformly positive.
