Hi Tony,
Your plastics work is beautiful. Top marks.
Small piece of advice for others though: I wouldn’t advise the tapping of those mirror pins for power as a general rule.
They’ll be supplied by a fuse closely rated for the intended task and adding unspecified load could cause a blown fuse. It may also cause and ‘Electrical consumer’ warning on the dash.
Always best to tap an ignition-switched source at a fusebox. I appreciate this is more work, but it’s the right way to do things.
In a worst case scenario, if your vehicle develops an electrical fault and the vehicle has a DTC code in the system that directs your dealer to a DIY job of that nature, theoretically, you could have your electrical warrantee pulled.
Just a friendlt FYI.
Otherwise, love the spec of that machine of yours with B&W + alcantara headliner. Oh to be living in low-tax USA!
(Also note the EU licence plate on the wall... which country?)
