Finally connected my USB-A / USB-C / 12V cigarette lighter socket...
Didn't use any fuse taps (what was my initial idea). Decided to add extra three circuits directly from fuse box located under passenger front seat.
That fuse box is powered via red wire which means there is permanent power (that's why I used also on / off switches).
- middle of front seat (where also are on / off switches - usb in the middle can be powered on / off via one of them)
- USB-A / USB-C in the middle of the van (ceiling)
(it can be powered of via second on / off switch located at the middle of front seats (please see above)
There is a single purpose of that - fan for my dogies

. Believe it can be quite beneficial during hot wave.

It has been fitted to the pillar C with 3M tape - still over there
- cigarette lighter in the boot (there is no extra switch - just secured with a fuse. Cigarette socket with no LED (for test purposed put usb plug over there)
The fuse box ...
... part number is 4F1 941 824
Dedicated crimps for that box are needed. Got them from e-bay as they were much cheaper then on amazon (approx £3.5 or so vs £15)
For wiring I used 12AWG (tinned copper) cables (~3.3 mm2).
The locker (purple - please see below) needs to be opened in order to put new cable to fusebox.
Cables went at pillar "B" and then under the ceiling - exactly where original cables are located.
For insulation I used fleece tape (approx 12-15m all together) and a bit of split conduit.
Because of the cable size I had to use "yellow" crimps. It's great to have few of the flag crimps as well (socket in the boot is connected with flag crimps)
(please see example below)
Fully recomend to use proper crimper to
All works (at least for right now) well
