I installed the newer version of this wheel using this DIY as a suppliment guide to the BMW instructions. Worked out great and is an identical install. Thank you for the DIY.
Some notes during my install...
A1 + A2:
I had no issues connecting those to Pin 1 (RED) and Pin 12 (Brown/Black) on the CAS unit under the driver's side dash.
I used a snake and snaked the wires through the center without the need to remove the center console.
Air bag wiring connectors:
The air bag clips are supposed to be pryed opened from the wired end not the other end. There's a small indention on the clip that is meant to insert a small flat head to pop the clip up.
Thanks again for the great DIY.
Here's a video I made of the new wheel in DEMO MODE that shows all the features.
