Several people have asked me about the harness I made for my SMG steering wheel with paddle shift retrofit and I promised to make a DIY writeup. Here it is. It is pretty simple and the main benefit is to avoid wires splicing and the retrofit becomes easily reversible.
The retrofit itself is already very well described by

Moreover, I found a post about harness as well (by

Not all information is completely correct in the harness post, btw (wrong list of parts). So, here is my version.
All parts are listed here:

You will need:
1) One large blue plug, 4 pol, p/n 61136925611 (item #5 on diagram, male)
2) Two pin-contacts, p/n 61130005198 (black) for the connector 61136925611
3) Two pin-contacts, p/n 61130006664 (black/red) for the connector 61136925611.
4) One large blue plug, 4 pol, p/n 61138380696 (item #4 on diagram, female)
5) One small blue plug, 2 pol, p/n 61136925634 (item #1 on diagram, female)
6) Three bushing contacts, p/n 61130005197 (black) for the connectors 61138380696 and 61136925634
7) Three bushing contacts, p/n 61130006663 (black/red) for the connectors 61138380696 and 61136925634.
Parts 61130006663 and 61130005197 are almost identical and you can get 6 pieces of either of them instead of 3 and 3. The only difference is in color of the wire, which I found useful and convenient. Same is for parts 61130005198 / 61130006664 - the only difference is the color and 4 pieces of either of them will work.
Also get thermal shrink wraps in nearest Home Depot, Lowes or Radioshack (I don't like the latter one because it is so overpriced!).
Now, the pics and measurements of the harness.
The total length is about 39 inches:

Here is the schema:

I didn't need any additional wires since I reused wires I cut from contacts I used in the short part of the harness (each contact comes with 1 ft wire attached to it; you need 1 inch of them for the short part of the harness). I think the pics and schema are self explanatory, but if you have questions feel free to ask.
