If I'm reading this correctly you're still not grasping that the chromatic glass needs different (additional) control circuitry within the mirror in order to make it work.
There are no additional wires that you can 'pull through'. Inside the mirror is a control unit which only requires 3 incoming wires; Power, ground and data. Those 3 wires are sufficient to control all functions of the mirror. Coming out of the control unit (the spec of which varies according to equipment level) is wiring to run the individual functions of the mirror. Ie. Movement, heating, folding, dimming.
On a low spec car with only movement and heating there are no wires present for additional functionality.
A folding mirror (but not dimming) has 1 extra set of wires to the motor.
Chromatic mirrors would also have folding as the options are bundled but crucially they also have further additional wiring to operate the chromatic glass.
