jphughan,
Thanks for all your feedback. I did make a back up. That was the first step before attempting to code. However, I was unclear in reference to what to look for when pulling the new traces of the CAS and KOMBI modules.
I admit the process is not user friendly, far from it actually. But how else can one learn without attempting. Unfortunately, the NCS_DIY offers a basic introduction. The rest is left up to researching and the general consesus is to ensure you are doing it right the first time in order to avoid headaches in the long run. Hence all my questions...
