5th Wheel/Gooseneck Wiring For A 2020 Chevrolet Silverado 2500

Question:

I just purchased a 2020 2500HD and had the gooseneck hitch installed. But it didnt come with the wiring harness standard on the 3500 or the 7 pin/4 Pin plug in. Chevy kindly predrilled the hole though, so I am limited to getting the exact size to ensure it covers the entire hole. Problem is, the parts department cant figure out which part to order. They keep wanting to give me the one listed online which is too small to cover the entire hole. Anyone find an aftermarket one that works?

The Pollak 5th Wheel / Gooseneck T-Connector with 7-Pole - Ford, GM, Dodge, Nissan w/ Factory Plug # PK11893-11932 is confirmed to fit your 2020 Chevrolet Silverado 2500.

This socket will plug into the T-connector to provide a 7-pole trailer connector in the truck bed for use with your fifth wheel. The connector plugs into the OEM wiring harness which allows for a 7-pole connector in the truck bed.

The connector is sealed with silicone at the back of the socket and prevents moisture from contacting the mating connector.

The recommended hole cutout for the connector in the bed is 2-1/8 inches.

I attached an installation video link below.
