I can’t tell you exactly which wire it is that would cause this, but whatever wire you pulled is very likely to be the cause of all these issues. It sounds like it was a main power or ground wire for multiple systems, since powers and grounds are often shared across multiple circuits. If you’re unable to properly repair the wire yourself, I would suggest having it done by a qualified professional, such as one from YourMechanic. They will be able to diagnose the source of your electrical issues firsthand and fix the problem accordingly.

VCM (Variable Cylinder Management) is fuel-saving technology that automatically deactivates 1/3 or 1/2 of the cylinders, according to the driving conditions. This saves fuel and lowers emissions.
There have been issues in the past with cylinder deactivation not work as well as the manufacturers might have hoped. However, with new vehicles cylinder deactivation does not usually cause those problems. Instead, it allows you to take advantages of premium power when you need it and save on fuel when you don`t.
