Hey Keith, did the wiring information for the Optronics Smoke Lens ID Light Bar help you get everything set up? I'm asking because your experience could help others who are working on similar projects.

@JonG I am curious I am running a 7pin to a junction box then spiting my wires at the junction box to run down both sides of my trailer. What color wire on these lights do I use on the turn signal for these wires? Or do I need to run a 4 pin.. first time doing trailing lights.

@Justin The common wire colors for trailer light functions are the following: Green - Right turn/stop Yellow - Left turn/stop Brown - Running White - Ground It doesn't HAVE to be these colors, but it does help to keep things consistent!
