so finally, those kits with cancellers are a waste of money and time?

No. It's been attempted by a member here before and only the parking lights and brow worked- the wiring harnesses were different and he was never able to get the HID's to fire.

As far as being plug-and-play, the ST3 HID's will not work on any other car other than the MK3.

I'm sure someone who is electrically inclined can make the necessary modifications to make them work, though. Not something I'd attempt, if for no other reason than the possibility that the BMC would throw a fit about it.

I built my own harness but you can purchase kits on eBay that will do the job.

http://www.ebay.com/itm/HID-Xenon-Co...044aa6&vxp=mtr

The one I bought did not come with the right connectors despite me asking for H11 so I was forced to do a little modification. Your luck on eBay may vary.

Essentially you plug a resistor into each headlight connector from the Focus. This tricks the computer into thinking you have halogen headlights installed and eliminates the "Dipped beam fault" error. Next, you use a relay to feed power from the car battery to each HID ballast. Note, some kits power each ballast separately and some kits have a single power connection which powers both ballasts. Finally, power from one of the headlights (it doesn't matter which) triggers the relay when you turn the headlights on.

To review, when you turn on your headlights the resistors fake out the computer and allow power to flow to the headlight connectors without a fault. From there the relay kicks in and feeds power to the actual HIDs. It sounds complicate but it's really very simple. Note, the resistors should be mounted against metal so they can properly dissipate the heat --and they do get HOT!

It would be cool if there was a computer recalibration mode where you could change your headlights to HID and replace the other lamps with LED and then teach the computer to learn the new "normal" for voltage and current. Right now the only work-around I've found is by using resistors and relays to trick the system. Effective but very inefficient.

I suspect the kit I received from eBay would have been plug-n-play if the vendor had sent me the right connectors.

What I can't believe is that Ford doesn't include HID lamps as standard equipment. The cost is minimal and the improved brightness and convenience would certainly be worth it. I could certainly live without frills such as the multi-colored LED floor lighting in my 2012 SEL in exchange for more useful features like HID headlights.
