I bought a 2017 ram Laramie longhorn limited back in Oct 2021. It had after market tail lights already installed. I found out that the lights that were in it aren't for trucks with factory LED tail lights. Videos I have seen show two wires for the tail light. The top is a 5 pin connection and the bottom wire is for the back up light. My truck only has the top pigtail 5 pin connection. My question is, do some trucks only come with the one top 5 pin pigtail?
