I have an 06 330i that did not come with any kind of cruise control. I am going to fit an LDM module and a new cruise control stalk.
I am trying to get 544 which is cruise control with braking which is not the same as in the video.
Can I still tap into one of the empty pins on the cas connector to power the LDM?
Is there a guide I can follow to wiring up and coding the LDM for my application?
I have like a thousand tabs open but none really explain how to do all this.

Hi BIZKIT551,
Its been a while since I did my retrofit, but I downloaded and followed Nicko43's DIY from the 1st post on Page 1 of this DIY. I then put together a simplified wiring diagram you can find on page 17 of this DIY.
For coding, I'll paste in below some notes I made whilst doing my retrofit, but the biggest problem you're going to face is that if your car has never had cruise control fitted before, then your DSC module will most likely be the basic one
WITHOUT braking function. You will then have to also replace and recode your DSC module with one that has braking function if you want to get this to work. My coding notes below won't have this as I already had $544 cruise with barking function factory fitted. You'll have to search elsewhere for that as I've never done it, but I think some have, I'm not sure.
Here's a copy/paste of coding notes I made when I was preparing to start. I will put in a caveat that there might be 1 or 2 extra steps or slight changes, I can't remember, as I was also doing things on the fly and your cars coding might be slightly different. If you do run into any problems, I'm sure someone else here will be willing and able to help with advice. Hope they help.
CODING
Coding programs needed are NCSExpert, INPA, ISTA and WinKFP. Delete $544 and add $541. Write the FA to the CAS and FRM modules. Then code the VO to the DSC, Kombi, LDM and CCC/CIC modules.
