Rear door wiring (460)
If the multi-core wire has the number of wires needed and the wire to the heated rear screen is heavy to carry the load, fit for the purpose. If you are proposing to retain the same route of wiring the job is straight forward principally however if you are proposing to re-route the wires as is done on the W463, internally between the pillar doors then that requires some drilling (Not easy) and more components to achieve the re-routing.

I can't remember. Does yours have the plastic trunking that slides in and out of the door pillar?

Good news about your wiring. Dubious information about your phone! Just try a different Web Browser in the phone.. download Chrome from the Android Play store and that will give you the Web view of the GWOA site, including the ability to upload a file from your phone, if you can find the file in your DCIM/images folder or wherever your pics are. I tried it on mine (new!) and it works. Pretty sure my older one would have too, going back 5 years or so.
