Loads of 'em, have a good look at the pictures.
Not sure if all this stuff works together or is in any way complete. I think there are bits from two or three different systems, the few instructions are French but have clear diagrams.
The break out boxes are marked for 206,306,406 and include BSI, Motronic 7.4, climate, instruments, power steering, abs, radio, etc. etc. Think the newer stuff is for use with Diag2000 or Planet.
Must have cost thousands new!
First £100 can have the lot, otherwise its for ebay.
