Canbus decoder in a 2006 ram 1500

Hello, it's just not a good idea to try and "retrofit" LED lights for a vehicle that was not original equipped with them. Depending on the set up and quality of the components, you can cause many issues with body control modules and even possibly interference with powertrain controls. Further, you could cause concerns with power output causing damage to wiring and connectors. If you insist on making this modification, you'll need to seek the guidance of a professional technician near you with strong electrical skills. There is no "plug and play" solution, and this forum really speaks more to factory equipment of vehicles, maintenance and repairs. Good luck!
