Schematics - Trailer Interface Module
In the USA, BMW doesn't make a trailer hitch for the F07, or for all of the other vehicles (only a select few). As a result, they don't put the trailer harness make ready plugs in the vehicle. I was given an OEM F10?/F07 trailer interface from another market for free, and would like to use it. The instructions are pretty simple, essentially, just plug it in. Problem is, in my vehicle, they didn't install the plugs!
So, if anyone has one installed, or has access to the schematics for the interface module, I'd love to hear from you so I could patch it into my vehicle! I need the pinout for the interface module. It's a 2011 535GT (USA), if that makes any difference, but I don't think it does. An (much more costly) alternative, Right Connections in the UK makes a package that is supposed to work (and I'm sure it does on the UK vehicles), but they would not guarantee it would work on the USA model, so I'm reluctant to spend the money.
While there are other CANBUS based passive interfaces that could give me lights, I really only want to disable the PDC when I have a bike carrier installed - the alarms are very annoying! I've got a light bar I could plug in, if I could get it wired. The factory interface (and supposedly the Right Connections one) recognizes when a trailer harness is plugged in and disables the PDC, changes the rear view camera view, and modifies the stability control...the aftermarket interfaces that just get you lights, don't.
It appears that the same interface module is used in most new BMWs. So, if anyone has one installed and would be willing to play a little and knows how to use a multimeter, it would be possible to figure out the pinout of the module and I could use the one I have. Anyody?
