so i decided to put a hitch on my 2010 s. that was pretty darn easy. the wiring harness that they sent me leaves me scratching my head a bit. ive looked all over the net trying to find a decent wire diagram of the tail lights and turn signals. there is no color code description that i could find. im hooking up a standard flat four plug system with pulse. does anyone know the colors of each of the light elements on the 2010 mini s?
i was thinking that myself but im in somewhat of a pinch to get this done. id need to order it in here. hauling my 73 cb500 yoshimura to a show on sunday.
I'm familiar with the site, and unfortunately starting from a few months ago, the diagrams are no longer there if you drill down and actually try to open one. There is another site that also used to work (http://wds.spaghetticoder.org/) but BMW has taken it down. Perhaps these are related events. If you need something in a hurry, you can purchase a one day access for $30 at: http://minitis.com. I haven't seen the newer Haynes manual that covers 2nd gen, but I have their 1st gen manual and the wiring diagrams are excellent: http://www.gbmini.net/wp/2005/11/the_haynes_manual_for_minis/
I have the Bentley manual and have to say the BMW wiring diagrams are pure horsesh1t. The amount of coding and lack of plain simple English is astounding. That's Germans + electronics for ya. You are probably better off having a helper push the brake pedal down while you probe at wires with a multimeter.
We have created a wiring diagram that we send out with all of our hitch systems from Minifini. If you message me with you e-mail I can send you our diagram.
Here, I would put the blame on Bentley alone. The BMW wiring diagram (WDS) is an interactive computer program. You can click on connections, zoom in/out, view connector pin configurations, photo of location of a connector in the car, etc. Everything is hotlinked and you find things in a few mouse clicks. Bentley went into the BMW WDS and basically took static screenshots of all the diagrams and chopped them up to fit on printed pages. Really horrible. Haynes actually redrew the diagrams into something readable.
