I have retrofitted a NBT in my PRE-LCI F11 everything is working except the Center Console buttons (Of course of the Facelift Uses the ICM2 module for this) 

Anyway, i'm making a piggytale Cable, so i coan revert back if i for some reason would want to.

Everything is connected in both ends except from the Pinout that will go to the center console buttons (I will fix this once i'm in the car)

But anyway, i guess i'm not the first here to do this (as it also will give me the ECO Pro modus and if i will ever install a NBT withouth built in GYRO that won't be a problem)

But what i'm wondering about is the 2 cables from the ICM 

Pin1 (Airbag Sensor positive connection Which goes to the crash safety module pin 30) and the other 

Pin1 (Airbag Sensor negative connection Which goes to the crash safety module pin 29)

Do you actually conect these cables to the CSM module or what? i mean as the Pre-Lci models dont use the ICM for this.

preLCI ICM from 9/11 use 2 wire connection and LCI ICM from 7/13 use 4 wire connection to the ACSM module.
ICM pin1 to ACSM pin30 all time positive ZXY+
ICM pin2 to ACSM pin29 all time negative ZXY-

Ok, so i guess i will need to connect 2 wires from my ICM to the ASCM module then?

On F10/F11 you will find 3 different ICM's

- old one up to build date 08/11 sensor in center console
- new one from 09/11 to 06/13 with 2 wire connection to ACSM (with GYRO)
- LCI version from 07/13 - with 4 wire connection to ACSM (with GYRO)

On F10/F11 you will find 3 different ICM's

- old one up to build date 08/11 sensor in center console
- new one from 09/11 to 06/13 with 2 wire connection to ACSM (with GYRO)
- LCI version from 07/13 - with 4 wire connection to ACSM (with GYRO)

Yeah, build date of mine is 28th of september 2010, so i have the version with the center sensor, but could i just keep those cables connected to the center Sensor? or do i need to attach them to the ICM which came from the F10 2015 ICM i bought? the ICM came with the 2 cables to the crash module, grey (ZXY- pin29) and grey/red (ZXY+ pin30)

See attached picture, its the twisted pair.

I think you need 4 wire connection for ICM high v5.4. This is for salapa 5AT, 5AR or 5DP
You have ICM low with smaller version.

Think i will just try and leave those cables and see if everything works, i have followed this DIY and the guy doesn't mention anything about those cables, same as Gizmonder which he used as a DIY for his own DIY.

Looking to do the same retrofit as you, any update with ACSM wiring?

Also, where did you find female connector for old ICM?

Thanks!

Hi there, no i haven't completed this yet, will install it in the car then the weather is better, although my father in law has this big garage, i have to drive like 7km's to it and it's kind of in the middle of nowhere so if i forget some tools or something i have to drive all the way back again.

Kufatec makes a 54pin female connector.
