I bought a Ram hitch light. The cord goes through the hitch shaft and under the truck, I have an “T” harness that keeps my bumper light plug stock while allowing for the hitch light to attach under the truck. The extra length is wrapped around the frame and after 34,000 miles... no shredding, pinching or wearing. I forgot where I got it but it’s called an “T tail light harness.” Good Luck!
