I just bought a 2004 Mini Cooper S and am modifying it to be flat towed. I'm installing a wiring kit and need to know the pin out for the wiring harness. I've looked at several hundred images attributed to this, have yet to find one.

There are five pins on the assembly and three lights. My "research" tells me this: Brakes -> bottom light; running lights -> bottom light; Turn signals and flashers -> middle light (yellow). I cannot find anything that activates the top light (which is red). The bottom light (red) has a bulb with two elements, one for running lights and a brighter one for brake lights.

I'd like to get a wiring diagram of the two tail lights, since they share only the brown wire in common. I've seen some You Tube videos, including one that had blatant and embarrassing errors in it which makes me suspect the rest of the video.

I've also been searching for diagrams and its remarkable how similar "Mini Cooper" and "Sienna" must sound to search engines.

I am unable to provide a screen print from my scan tool of the wiring diagram for both tail lights for a 2004 Mini Cooper. Add a comment if you have questions and I will do my best to answer them.

The left tail light has three bulbs - PARK fed by GRY/VIO wire, TURN fed by BLU/GRN wire, BRAKE fed by BLK/GRN wire.

The right tail light has three bulbs - PARK fed by GRY/YEL wire, TURN fed by BLU/BRN wire, BRAKE fed by BLK/BLU wire.

The common wire between the left and right tail lights is brown.
