Short summary
What do you need.
- Steering wheel for paddle shifters (no matter if from a E90, E92, E93, series1 or M)
- Paddle shifters (the ones for the E90 have a different part number but they are interchangeable with the ones from the E92)
What you don`t need:
- a different slipring
- new multifunction keys
The multifunction keys for steering wheels with shifter paddles have a connector input that is used for the shifter paddles. This is a 3 wire connector.
If you cut off those connectors and connect like ska325xi explained in the first post you won`t be needing those new multifunction keys.
That colourful drawing on the first post should be removed or corrected. It is basically right but the colors are random. Contact 1 connects to contact 3 of the other shifter paddle, 3 to 1 and 2 to 2 which is ground.
In case you don`t want to cut any connectors and want to spend the money for new multifunction keys:

There are at least a dozen of combinations for the mufu keys, depending on what radio you have, if you have a navigation system etc.

Whatever version you get, they will all work the same. The functionality is not in the keys, all are connected in the same way, it is programmed. What`s different is the printing on the keys.
So now to actually doing it.
At first get yourself crimping pliers. They won`t cost much more than approx. $10-15 and you`ll do the job correctly. Do use the correct connectors and don`t try to hold non fitting pins in the connector with silicone or anything similar – that´s just wrong.
The correct BMW part number for the “pin connectors” mentioned in the very first post are
- 61 13 0 006 663 female connector
- 61 13 0 006 664 male connector
Nothing more to add. This was the steering wheel side.
For the steering column to shifter side do as described.
Those female connectors 61 13 0 006 663 are the same used for pin 2 & 4 of the slipring connector.
If you prefer to make a removable wiring you`ll need the original BMW parts:
- 2x connector housing socket (12 contacts) 61 13 1 383 736
- 16x bushing contact (female) 61 13 0 006 663
- 14x pin contact (male) 61 13 0 006 664
- 1x connector housing socket (4 contacts) 61 13 8 380 696
- 1x connector housing socket (4 contacts) 61 13 6 925 611
- a bit of wire 0,5-0,75mm²
Make 14 short cables with a male contact on one and a female contact on the other end.
Take the 12 contact housing sockets and insert contact by contact until each clicks in place One connector takes the female contacts, the other one the male contacts.
Note: it is very important to not insert any cables in the housing contacts 2 & 4 (of the connector with the female contacts) and 8 & 10 (of the side with the male contacts). Let these empty !
Make two 40” (1m) long cables and crimp a female contact on one end. Insert it in the free slots 2 & 4 of your 12 contacts connector. (Contacts 8 & 10 over the other side will remain empty).
You`ll have 4 short cables with contacts on remaining. Connect each of the long cables made to one of the short cables. Then insert the side with the male connectors in the (long) housing socket 61 13 6 925 611 and the one with the female in the short housing socket. The short cable connected to the long one that routes to pin 4 of the 12 contact connector goes into slot 3 and the one to pin 2 goes into slot 2.
That`s it.
Always disconnect the battery ground terminal and reconnect it only after you`re completely finished or your airbag warning light will be on and you´ll need to get the error memory deleted.
