Well, everyone, meaning steptronic owners that is.

I think we all agree that the illuminated M5 shift knob is very cool. Now I'm hoping that we can build an all-OEM kit that everyone can make for themselves. I'm sure with everyone's help we can do this.

I'm 99.99% sure I currently have, in my possesion, all the OEM parts needed to build a 100% OEM wiring kit. I realize I'm not technical enough to figure out the wiring so I'll be soliciting everyone's help to do this.

Required Parts

Shift knob product link:
Tischer BMW / getbmwparts.com
http://www.trademotion.com/partlocat...catalogid=4462

Wiring parts:



Other parts (optional):
- Heat shrink tubing for 18-8 AWG wires

M5 shift knob pin assignment
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

Wiring

Pin assignments and connections

M5 pin 1 -> White connector pin 2 (or 3 if you look at it as a 6-pin connector) (R)
M5 pin 2 -> White connector pin 3 (or 4 if you look at it as a 6-pin connector) (N)

M5 pin 3 -> Blue connector pin 4 (M/S)
M5 pin 6 -> Blue connector pin 5 (Zone illum)

M5 pin 4 -> Power connector pin 1 (Night illum - ground)
M5 pin 5 -> Power connector pin 2 (Night illum - +12V)

Where did you hear about this? How much did it cost?

[reggiecmah]

i am ordering a M5 knob from tischer soon here.
i will subscribe to see updates on the DIY

[phattbam]

here's a hint. I did this with my tinkering of my DCT/650 knob. I removed the shiftplate and had to test out those connections. I can post what I came up with when I tested it with a 9v battery.

Yes, if you could post some specific details on the connections.

Under the shiftplate there are 3 wiring connections:

1. Cigarette lighter connector (3 male pins, 3 female pins)
2. white connector (4 pins), and
3. blue connector (6 pins)

Now the shift knob has 6 pins and we need to find out how those 6 pins are wired to the 3 connectors I mentioned above.

I"ll have to get my laptop later tonight. I'll be on this thread though.

Cool. Thanks.

Btw, if anyone has any info on the pin assignments for those 3 connectors I mentioned above please share it to us.

[phattbam]

nevermind I found it... it was on my desk

for the white connector... with the Black striped wire as #1.

should I post an attachment that I can write up with a table?

Yep, pics/illustrations would be great.

[phattbam]

I dont have pics, but here's a chart I just drafted looking at my scribbles.

let me know if you have any questions on how to read it.

B=black wire from 9v battery[(neg)ground] R=red wire from 9v battery[pos)power]

Couldn't quite understand it. How do I read it? Also, what is the 9v battery?

[phattbam]

9V battery = the rectangular shaped battery you use for your smoke detectors in your home. I used that to test the connections.

so when I touched the black lead(neg) to the white/black wire (white connector) and the red(pos) wire to the #2 pin from the blue connector it lights up the P on the shiftplate.

Ok. Let me check it out again.

[phattbam]

I'm still waiting to get mine back.

Tuesday bump. We need more inputs to get this going.

i would be very interested if the the kit becomes available to upgrade to M5 knob

M5 shift knob pin assignment
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



The table in the word doc is in a strange format but if I read it correctly you can at least determine where the trans positions match up. Then you can figure out where to source your +12 voltage for pins 5 and 6 while its in the vehicle.

      Pin#                        Pin#   Trans pos
M5    1      -  White Connector    2     R
M5    2      -  White Connector    3     N 
M5    3      -  White Connector    4     D 
                or
M5    3     -  Blue Connector     4     M/S

Be careful about using a 9V battery to probe around. If the lights are leds you may inadvertently be pushing them into a reverse bias.

I got the pin assignment from the M3/M5 boards. But after seeing phattbam's chart I wasn't so sure if the pin assignments were right as they don't quite match up.

For the power source, we can use the cig lighter connector for that.

[phattbam]

I'm hoping that I didn't damage my LED set up on my knob as well it was costly to buy. Will keep you guys informed if I get it working.
