I just picked up a 2021 RST does Anybody know if there's a kit that will allow me to add another 4 pin connector preferably under the truck? I'm wanting to install a LED light bar under the tailgate but don't like leaving it plugged into the factory connector. I had one plugged into my factory plug on my 2018 model I just traded in and it became corroded after being exposed to the elements for so long and caused the light bar to quit working even after using dielectric grease liberally. I've look for a wiring harness for trucks without a towing package but apparently all full size trucks come with a tow package. Before anyone says it I'm not interested in splicing or tapping into the factory wires.
