I know it's been done, read a lot of the threads.
Anyway, my question is whether an '08 is prewired for a brake controller harness. I know the earlier BMW ones aren't but I couldn't find anything giving a 100% answer as to whether an '08 was or not. A lot of websites list a Ford/Lincoln/Mercury harness as the correct part, but just wanted to know before I ordered it.
I already have the factory wiring ECU/harness installed for the lights, and I'm about to order the hitch.
