Name That Plug?

[Mart Pug 0]

Found this under my AFM.

 

Can anyone tell me what it's for? The wire connected to it goes under the HT leads and down past the dip stick, then down to the back of the bottom end. Can see where it ends up.

 

 

 

Also seems to have some nice fraid wires near the plug:

 

 

Car is a standard 1.9 8v, apart from cone air filter

 

 

 

Should I be concerned that it's not plugged into anything?

This question comes up all the time.

 

The plug is only used by the Peugeot dealer diagnostics machine, and is of zero use to anyone else.
