Question:

Ive got a 2023 Silverado 2500HD duramax and am needing to hook up LED running lights for a truck bed camper. There is a 3 pin connector coming from camper. The truck has a 7 pin and a 4 pin flat connector at the rear of the truck. What is the best way for me to get these running lights hooked up in a neat way, if that is possible. Thank you in advance for any help you can provide.

Hey Doug. We don't have any 3-pin connectors so you'll first need to swap that connector out with a 4-way using the Hopkins Wiring Harness with 4-Pole Flat Trailer Connector item # HM38168. The functions for the 4-way are listed below:
Green Right turn signal / brakes
Yellow Left turn signal / brakes
Brown Running lights / taillights
White Ground

If you do not want to go all the way down to the 4-way connector on your bumper. You can install the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package item # C55384. This ties into your trailer wiring and allows you to install an additional 4-way connector in the bed of your truck.
