Hi, I am doing manual swap on my 330ci...I have read post about wiring 4 wires from clutch switch... If I bypass clutch safety switch with ncs expert/bmw scanner do I need to install fourth wire from clutch switch to my ews module?
clutch switch wiring to EWS after AT to MT swap

No, you don't. Clutch switch to EWS wire is only in US and JPN version loom. You just code the EWS to not check P/N/clutch for starting using NCS Expert.
Clutch switch to DME pin 23 however, is better to install. It's used not just for cruise control disable, but it also switches some engine behavior modes for driving convenience. When not connected, ECU seems clutch depressed all the time.

Thanks for the reply...so 3 wires: 12V, ground and wire to the DME and code ews with ncs expert/bmw scanner.... And than later code zcs because my car is 2000
Also code your instrument cluster for gearbox type. At least to get rid of gearbox failure symbol.
If you have PDC, you also have to connect reverse signal to instrument cluster to make it work.
Then you should reset all DME adaptations so it detects gearbox type automatically (not sure how it detects that) otherwise you will have high idle.
Connect gearbox reverse switch instead of reverse relay, but you already know that. That's all.

Yes yes, I know everything you mentioned.... Thanks anyway😁
I would run the clutch wire to EWS to do the swap correctly.

Absolutely follow @bali’s guide. Was a life saver.
So DME knows if engine is braking during coasting and cut off fuel injectors to save fuel and less pollution.
I'm sorry, but that is correct only for US and JPN version of the car. Clutch switch is NOT connected to EWS in European version cars. You can check that in TIS. I can also confirm, that clutch switch connector pin 4 is unpopulated in harnesses I took from local (German market) cars.I would run the clutch wire to EWS to do the swap correctly.

Also, the configuration rules for EWS default coding in NCS Expert says that P/N/clutch starting condition option is set only for US, JPN or AUTO option.
So the correct swap is:
a) US and JPN version: Connect clutch switch to EWS, no reason to code the EWS
b) other versions: Not to connect clutch switch to EWS, need to code the EWS
Also, is there any need to code default settings in all control units in the car? Most units have no option based on auto/manual option. I know only about instrument cluster and EWS.
How do you code the EWS? I read it using AK90, but will never try to write it.
Read it using ncs expert and open trace file with ncs dummy... First option(engine starts only in park/neutral) set to nicht activ... Save it as MAN file and write it to ews again.
Ah good points. I missed that OP is not in USA.
It is easier/safer to just code all modules, but yes you can just code the ones that matter.
Ok so in the end... I need 3 wires from clutch switch:12V, ground, to the DME pin 23.
Code ews module(engine starts only in park/neutral) NICHT ACTIV
change zcs and do zcs schrieben to KMB and EWS
(optional other modules)
Reset DME adaptations
Am I correct?
Confused. 3 wires from clutch switch wired to DME one pin p23? Only the sensing signal is wired to DME p23. sensor 12v and GND should be wired to the brake sensor harness for the power supply.
Clutch sensor has 3 or 4 wires? U.S. E46 M3 has 4 wires.
Third wire is to the DME. Only US and Japan market E46 had 4 wires.
Prculin2 If you still having some difficulty with this follow my signature to the "Official Automatic to 6-Speed Conversion". I just reapplied all the pictures which, show some physical detail and an explanation of the wiring that needs to be completed between the EWS and Clutch Switch Module - I think around post 21 or 22. I also created a wiring diagram that doesn't explicitly exist in the WDS but uses the same graphical schematic make up to depict this wiring step.
Thanks man, I'll take a look at it.
DME gets the vehicle order (ZCS or FA) from instrument cluster after adaptations reset.
Ehm, manual swap without removing the trans? I think that I don't understand that.
Reverse switch on the manual gearbox is the only thing, that tells the car that reverse gear is engaged. There is no other way because it's the only thing electrically connected to transmission/drive. I guess your reverse lights don't work then.
If you connect the wire from fuse box to the instrument cluster reverse input directly, it will sense reverse gear engaged all the time and thus will keep PDC active and mirrors dipped all the time.
