2004 bmw x3 park lights wire

I am looking for the wire for the park lights on a 2004 BMW X3. I found information stating it to be a brown wire at the light switch. I have a ribbon cable wire coming from a module to the light switch. Do I need to use a wire in this ribbon cable or do I use one supplying the module. There are three brown wires feeding the module. I think they all have the same colored strip.

if you are looking at the ribbon cable, seperate the 4th one from the left, cut this wire in half and wire in a relay this will get your parklights going

Is the 4th wire left from the stripe on the ribbon cable. The plugs are numbered. Is it number 4 wire? Does anyone have a description of what all ten of the wires do? I am having trouble with my dimmer not working.
