The wires look like they are there for Stage 2 JB4

This is an important thread as the notion that some BMW F10s may not be Stage 2 compatible may be inaccurate. I believe that the wiring harnesses are sometimes reversed and also think that the colour codes are likely consistent within a model platform. I have not had the chance to try this but I do think you should compare the pictures I have posted to your car and to the instruction picture on Terry Burger's web site and hopefully you can identify what I have seen. When I get a chance, I will likely try the upgrade and what we need to do is identify which wires we need to plug into. It may be the ones closest to the red wire in my picture on the left bundle.

Hopefully I will get a chance to take some even better pics on the left bundle connection.
