Hi Jeremy,

Thank you for your excellent posting. This information has been invaluable.

Silly question though - do you have the part numbers of the connector base and cover ?

Why ?

My W124 has this connector but it only has 5 sockets rather than the 9 sockets on the one in your W124. Only one of these sockets is unused in mine.
It would be useful to have the additional four sockets for accessories.

I know i can cram other wires into the existing plugs, but would rather use seperate plugs.

I am fitting door-bottom courtesy lights (+12v "hot" supply) and would like to fit a 5V regulator for 'phone and GPS (+12v "switched" and GND).

Cheers,

Neil xx.
