Help with cables and connectors

[ThiagoR]

Hi guys! I'm from Brazil and found this car here, it's a 735iL with EDC and ASC and manual adjustable seat
These cars are rare here, specially iL with M30. Most commom is 750iL and 740i.

So, I remove the rear seat and found a lot of cables and connectors, can you guys please tell me what was
connected before?





Under the driver seat

I did not buy this car yet, I'm trying do understand everything first to see if it's salvable.

Thank you!

The cars came with a lot of wirings/[lugs which are often not used, ready for most of the options, if ordered or not, especially the first built years.
Under the rear seats that could be for example the connectors for single electric seats, seat heating rear, electric headrests.
The round one with the many pics I have not seen before, maybe from a removed car telephone or car stereo.

Hi shogun!

Thanks!

BTW I Just bought the car, I found out that these 2 cutted cables were from original stereo with amp made by Becker.
