T-Connector for Light Bar Power on 2022 GMC Sierra 2500
Question:
Do you carry a Quick-connector that is a T-Style harness that allows continued use of the trailer hitch plug connector when using a 4 pin trailer plug with a light bar? Does it have a way to prevent the truck from thinking there is actually a trailer attached? GMC 2500HD AT4

We do have that style of harness for your 2022 GMC Sierra 2500:
Curt T-Connector - # C55384
This tees in behind your factory 7-Way and is perfect for a light bar. The only issue you're going to run into is your vehicle thinking a trailer is connected since a light bar will be drawing power from those circuits.
The only way to get around your truck thinking a trailer is connected is by installing a universal wiring kit like the Curt # C59236 which uses the light circuits as "triggers" and pulls power directly from your truck battery. If you do end up going this route then you'll need heat shrink butt connectors like part # DW05744-5 or # DW05745-5 so your wiring is better protected against the elements.
