So I did some research today into the wiring of the wing mirrors. Turns out that the wiring and connector for the Side assist mirror cap lights are present. The blue/yellow wiring runs from the wing mirror harness to the 4 pin connector in the door harness. However from there all the way to the rear of the car will need to be custom fit.

A few snaps...

I then had a look behind the door trim..






From door harness to the rest of the car, the blue/yellow wire isn't present. According to ELSAWIN, from this point the wiring changes colour to Purple/Blue.
