I believe you are looking for the stop light switch wire that was separate from the main brake controller harness on the 2013 and 2014 Ram trucks. For the 2015 models Dodge combined all of the brake controller wires back into one harness located near the steering column. It may be to the right or left of the steering column, so you will want to look for a white 4-pin plug that will be taped to another harness. We do not have a video, but I attached photos showing the connector. Look for a white plug that might be taped to another harness with another white plug. If you do not see it to the left of the steering column, try looking to the right of the steering column toward the center console, behind the dash.

Due to the sensitive computer and electronics on the new Ram trucks, I strongly recommend using a plug-in style harness like part # 3024-P. This harness was specifically designed for newer Tekonsha, Draw-Tite and Reese brake controllers, but you could simply cut off the black connector and splice in your brake controller if it is not one of these brands. The wire colors and functions are listed below for this harness are listed below.

Black - 12 volt power
Red - Stop light wire
Blue - Brake output signal
White - Ground
