First picture is the wires coming off my controller, brake control controller
Second picture are the wires hanging off of my dash to hook up to the controller. But you noticed the colors are different so I need to know exactly which wires go to which before I hardwire it. Only know two things the white coming off of the control controller is the ground. The blue is for the Trailer wires. The red is for the stop and the black is for the power positive battery. But the four wires hanging under my dash on my 2014 Yukon Denali is not matching the wires coming off the controller. The other time I did this to a 2010 Chevy avalanche the bundle had markings on the wires to which one went where. But this one, the four wires hanging underneath the dash have no markings. The only assumption I could make is that the blue goes to the blue and the black on the controller. If it’s the power, which one does it go through. The controller also says that the red wire coming off is for the stop switch. Is the red wire hanging? Also the stop switch wire. That leaves a yellow and a white so I’m assuming that the white is also the ground on the wires hanging, but I have no idea if I’m correct and what is the yellow wire for. I’m sure this has been asked 1 million times but I’m sorry I gotta ask again if somebody could please help me I would appreciate it.
