I have just purchased a 2021 Ram 1500 Bighorn and plan on adding side lights under running boards. These lights are led strips with amber for marker and turn, red for running lights and white for courtesy. The white is taken care of , I would like to interface with the OBD to activate the turn signals and marker lights, avoiding having to cut into the wiring harness. I must be using the wrong terminology in my search as I am sure there is an interface or something.
