Right Hand side auxiliary footwell 12V wire

Jean Mercier said:

Today I tested electrically the right side footwell auxiliary potential power point, and indeed: 12V, with PWR on and INT2 on on the "aviation" roof switch panel.

Some pictures:

Then I removed the tape around the wire, did cut the top of the transparent plastic protection hose of the wire, inserted some surgery needles in the top of the wire to have a metal contact (electrical contact), and connected a multimeter to the needles, with the negative to the black wire and the positive to the yellow/purple wire.
Only when switching on the INT2 roof button, together with the PWR on button, did I get 12V power on the wire!

The measurement of my multimeter was almost the same as the measurement of the voltage f the main battery of the car:

I then removed the fuse FI30 in the fuse box under the left passenger seat, and indeed, no power anymore on that auxiliary power point.

Not sure yet what I will do with it, perhaps a Deutsch connector, or perhaps an auxiliary USB-A + USB-C power point.

Fantastic work Jean. This could be a handy power source for a driver heads-up display

@Jean Mercier ~ excellent. Don't suppose you took any photos or could give any description of taking the panels off? Tips to avoid breaking any fragile clips etc...

So a supplementary question if INT2 does the right hand footwell via fuse FI30, does INT1 do the left hand footwell via fuse FI29?

And then what about the spare under seat/ fusebox outlets?

+1 for how to take the interior trim panels off.

• first remove the "footwell step", or how is this called ("Trim Panel"), pull it straight up.

• Second, remove the floor mat, but first remove the plastic screw (in my case under the fire extinguisher):

• Third remove the screw of the plastic wall cover at the right side. Don't forget my car is Left Hand Driving (but for Right Hand Driving people, everything is at the other side of the car!), This picture was taken afterwards, without dismounting the floor mat.

• Fourth, put your left hand (again, don't forget I have a LHD car) as high as possible with fingers behind the piece and tear it of as straight as possible. And here you are ...
• Fifth the "pillar piece" looks like this, and don't ask me questions about that hole I made ... you will understand without words, but look at the clipping parts!

• I hope I forgot nothing

OK, let's go.
First thing, remember that I have for sure a wrong wiring: INT1 and fuse [EDITED] FI28 are connected to the exterior DTP roof connector right side front!

Taking it off (with small damage, I mean one or two plastic pins slightly bent):

• first remove the "footwell step", or how is this called ("Trim Panel"), pull it straight up.

• Second, remove the floor mat, but first remove the plastic screw (in my case under the fire extinguisher):

• Third remove the screw of the plastic wall cover at the right side. Don't forget my car is Left Hand Driving (but for Right Hand Driving people, everything is at the other side of the car!), This picture was taken afterwards, without dismounting the floor mat.

• Fourth, put your left hand (again, don't forget I have a LHD car) as high as possible with fingers behind the piece ad tear it of as straight as possible. And here you are ...
• Fifth the "pillar piece" looks like this, and don't ask me questions about that hole I made ... you will understand without words, but look at the clipping parts!

Champion thank you, have to wonder what the yellow wire is.. signal wire of some sort?
