I recently bought a Focus Mk2 1.8TDCi Ghia 07 plate and decided to fit a hands free kit. When fitting I noticed that on the panel under the radio there are 4 slots from left to right as follows;

Blank - Headed windscreen - Heated rear window - Blank

The far left blank has a connection to it but it is blank, does anyone know what the wires are for or if they even do anything? Would buying a button for it make it function?

Any info would be great, thanks

 

IIRC correctly the left one is where the button goes to disable the traction control, the right one is for the roof on the CC
