Hello,

Going into my 3rd brake light (LED) I have four wires, black, blue, white and orange. Does anyone know which one controls the brake lights themselves? I'm trying to install a flasher.

What do yo mean by “flasher”? The 3rd brake lamp is driven by an FET in the BCM; attempting to install anything aftermarket in that circuit will cause problems.
