Yes, plugging the modular plug into the other component was easy, it's the setting that set-up of having to make anme ambiguous hole in the wall that's the problem.
What if the wall is cinder block, or tiled? One would also be breaking a fire stop by making these holes that are right above a kitchen stove.
No other major appliance I know is such a convoluted install.
Just move the appliance in, plug it in, connect water or gas, vent line.
