Wow, what a great news from Idaho!!!
And a very long journey over 3.5 months!
Congratulations on the IMHO worldwide first replacement of the hydraulic wiring harness with a homemade one.
Btw, do you have some pictures of your rebuilt harness for future reference, when BMW will not be able to deliver replacements any more?
That's pretty cool that I might be one of the first hydraulic homemade harness. I do have quite a few photos and I made a short video going over all the things I learned through the process as well. I will spend some time putting together a new thread and post all the findings, photos, videos, etc. Hopefully that will help someone in the future that wants to go the route I did (or full harnesses are no longer available).
