The beauty of global closing is when you press the open or close button & keep it pressed for3-5 seconds it will open or close all the windows together . Just brilliant. even my mirrors fold remotely.
I should have done this ages ago but didnt have chance. I bought the focus mk2 /2.5 usb/ aux switch which replaces blank switch. But didnt wire it up. Behind the stereo their us a multiplug for 12v outlet taped up in the loom just below the radio. ( note this might be already used up on non keyless keyfree push button engine start cars. As mine has push start button where other lower spec models have 12v power outlet next to gear surround.
The switch has a push in button for power on & illumenates.
