Default M5 SMG knob does work 100% in an M3!

I installed the M5/M6 shift knob in my M3 by getting the information in this thread:

http://www.m3forum.net/m3forum/showthread.php?t=83712

Thanks to: tlp, MITE46, and BimmerPerfStore who made it possible for me to make my install.

If you decide to perform this mod you are doing it at your own risk. I am not guarantying that it will work after following these instructions. I also do not know what effect this mod may have on the car in the future. Now that being out of the way; following are the step by step instructions on how I did the install. I wanted to make the installation 100% reversible in case I wanted to remove the knob and/or not cut any wires to void any warranty.

Material needed:
*M5/M6 Shift Knob – I purchased mine from here https://secure7.nexternal.com/shared...t=products.asp

*6 way connector & 6 Bushing Contacts – Dealer http://www.m3forum.net/m3forum/showp...7&postcount=10
*Wire striper
*Electrical tape
*22 gauge solid wire (for tapping into 12V) – Radio Shack
*18 gauge Standard Wire (for gear selection; R, N, D/S) – Radio Shack (20 gauge solid wire may work better)
*Tap-In Squeeze Connectors (blue in color) – Radio Shack
*small flat screw driver
*pliers
*Zip Tie – Home Depot
*Amazing Goop (glue/adhesive) – Home Depot

Reference:

If your car displays N (instead of 0) when neutral is engaged, then the M5 knob will work 100%; otherwise, knob lights will turn off when shifting down. I don’t know this for sure but that is the understanding I got from this thread. http://www.m3forum.net/m3forum/showthread.php?t=83712

M5 shift Knob wire label:


Pin# - Description

1 = Zone Reverse (GND)

2 = Zone Neutral (GND)

3 = Zone Drive A/S (GND)

4 = Night Illumination (GND)

5 = Switched +12v for Night Illumination

6 = Switched/Constant +12v for zone lighting


1. Cut a small piece of 22 gauge wire and strip one end.
2. Cut three small pieces of the 18 (or 22) gauge wire and strip one end.



3. Push the 6 busing contacts (wires) into the 6 way empty connector and then make the connection with the shift knob.








4. Connect the 22 gauge wire (non striped end); using the Tap-In connectors (blue), with the Pin #6 wire of the knob
5. Connect the remaining three 18 gauge wire (non striped end) with the remaining three knob wires.

6. Remove OMG SMG shift knob pulling up firmly. Once the knob is loose, pull up on the gray plate



7. Disconnect the green SMG Shift Speed Selector connector.
8. Strip wires 4, & 5 of the shift knob
9. Follow the instructions on this post for wires 4 & 5 of the shift knob: http://www.m3forum.net/m3forum/showp...&postcount=100 instead of cutting the wires simply push the shift knob wires 4, & 5 into the SMG Speed Selector connector (Green) and tape it up such the wires stays in place.
10. Test the connection by turning on the parking lights. Turn of the interior lights so that it doesn’t flood the knob lights. Celebrate your achievement and move on to step 11.
11. Remove the SMG Control Module 12 way connector (not sure what it is really called).



12. Remove the housing to expose the connector.





13. At this point there should only be 4 wires remaining to connect. Connect wire 1 of the knob to Pin #3 of the 12 way connector. Again simply push the striped end of the wire into the back of connector. Continue making the connection with Knob wire 2 to Pin #7, Knob wire 3 to Pin #8, and Knob wire 6 to any of the two red/white wires.

Knob PINs…………………………………………….…. 12 PIN Connector (SMG2 Control Module)
1 (Zone Reverse GND) ==connects to == 3 (WH_R2; grounds when engaged)

2 (Zone Neutral GND) ============ 7 (WH_N2; grounds when engaged)

3 (Zone Drive A/S GND) ========== 8 (WH_S2; grounds when engaged)

4 (Night Illlumination) =========== already connected in above steps

5 (switched +12v for night illu.) ===== already connected in above steps

6 (Switched/constant +12v) ===== 12V (connect to 1 of the two red/white wires)



14. Once the wires are in its correct location. Turn the ignition to position No. 2, apply parking brakes, and cycle through R, N. and D/S. Knob should light up as gears are selected. If the test is successful move on to next step; otherwise check your connection.
15. Start tapping up the wires such that they remain in place.
16. Replace the housing on the 12 way connector. You may have to massage the wires to make it fit.
17. Place or Connect the 12 way connector it its original location.

M5 shift knob’s leather boot did not fit in the M3. There might be other alternatives, but here is how I made it fit.

18. Remove the plastic connector from the boot of the M5 knob and from the M3 knob.
19. Place some Amazing Goop around the M3’s boot connector.
20. Place the M5 knob boot end around the M3’s connector.
21. Use Zip Tie to hold it in place for few hours. I left mine overnight.




22. Connect the SMG Shift Speed Selector connector (green).
23. Connect the M5 knob with the 6 way connector you just installed.
24. Snap the gray tray back in its place.
25. Push on top of the M5 knob to snap it in place
26. Turn the key to Position 2, and apply brake
27. Cycle through the gears to ensure everything is working.










Let me be the first to congratulate you on your install. Congratulations.
