Welcome to the forum, our info showed two possibilities for the wiring circuit, with and without bulb outage module, if that is what your talking about?. The top violet wire is voltage to the module, if you have one. The other violet and violet with black tracer is voltage for left and right lamp assembly, brake lite. Whether you actually have that module, I don't know?
