"In this video we are going to show you how to install an OPT7 LED Tailgate Light bar on our 2018 RAM 2500 or any 4th gen. Instead of quick connectors and butt connectors we chose to solder in an extra harness connection to our existing trailer connection module by de-pinning it so we could hide the light bar wiring completely under the bed. This also provides you the use of your 4 pin connector for towing at the same time. We are using a butane soldering iron which is my preferred choice for solder connections on most anything. Hopefully this video helps you with determining what specific light bar you may want and how to install it on your 4th Gen Ram Truck."
