16097 Customer Satisfaction. Some vehicles had TRAILER WIRING, DUAL 4-pin/7-pin SEALED CONNECTOR, listed on the window Label. GM charged for but did not ?loose ship? the connector when it left the assembly plant. Customers with this condition may contact their local GM dealer to communicate their VIN, and the dealer will arrange to provide a dual 4-pin/7-pin sealed connector for them to pick up at no charge. Dealers are to place the part in the glove box for inventory vehicles. Dealers are to tighten the transmission mount fastener to specification.
