There are some redundant plugs in the place you describe.

Can you take a picture of the suspect plug and attach it?

Here is a picture of the BSI (which may help?)

There is a circuit diagram in the haynes manual for the C3 that describes sockets/plug colour and wire colours.

This a picture of the wires and plugs/switches attached to the brake pedal on a manual

The blue and black sockets don't have anything connected to them , but there isn't a loose plug needing a home.

If you need to have you foot on the brake to start the engine, you could have a problem with the pedal switch?

Its not so tricky to remove the whole glove box for a better view, just some torx screws once you get the door off (more torx)
