Can confirm above
I usually chime back in after my installs to give a report of how it all fit together but yes, the above post is correct that 61131378908 does
not fit correctly. It holds the black plugs/cigarette wiring fine but it is too shallow to twist into the center console mounting point. I had to shave down the edges to get the locking block to fit and twist snuggly. It looks OEM enough but obviously is not the correct part number. One day I may try to track down the true part number but for now my solution was adequate. Apologies for everyone I've inadvertently mislead
Also do not order the above mentioned part number for the wiring tape, it is like Velcro and super thick; it does not match the fuzzy electrical wiring tape BMW used for our harnesses. Just Amazon "BMW Tesa Tape" it's a close enough match and runs $15 for 75m. That's probably enough to rewrap every harness in the car maybe at least once
