Me too! Would like to add center markers to mine also. 2022 SRW 3500@Jimmy07 , I wonder if you can make a harness that would allow me to plug in the 3500 DRW rear center marker lamp to my 2022 3500 SRW truck?
The one I used came with a connector that splits the trailer harness. It’s plug and play.Have you installed ? Wondering if there’s an open connector or cut and splice?
