Hey everyone - I'm working on a project using an E90 6 spd with the ATC300 transfer case. Since this drivetrain isn't going to be controlled by the xdrive computer (and I don't see any aftermarket options) I am setting out to build a PIC-based transfer case controller. I could only find a wiring diagram from later X3/X4 but the wire colors aren't the same.
Does anyone have a copy of the diagram for the 7 pin connector as well as the 2 pin connector hanging off the end of the actuator? Thanks!
