Guys around town love the look Review: Works on 2023 GMC Sierra 1500 - Super easy to install. I can confirm it works on a 2023 GMC Sierra 1500. I wasn't sure but I took a chance reading of one or two other reviews here on desertcart as well as the OPT7 website, so I wanted to verify it for everyone else. It plugged right in. I had it installed for testing in 5-10 minutes, no tools. Completely done in 15-20 tucking the wires and zip-tying up. Plugged in my rear tailgate light bar and it worked as it should, using the tail-light relay rather than trailer-plug relay. No errors on the truck when I started it, lights looked great- running, left/right turns, reverse. Very happy with the purchase. ## Features - [100% PLUG'N'PLAY] Perfect match with OPT7 Redline LED tailgate light bar.
