Need some help from you HID people, fitting not gone to plan.

I ordered a set of HID's for the track car, came today. Fitted them as per instructions. Everything the way it said. Went to turn them on... No light

I don't get it, because the lights are getting the power for the hi/low beam switcher. You can hear and see it. They are also getting power to side lights and levelers. The only thing that isn't working is the HID bulbs. It can't be a abulb or a ballast as neither are working. It must be something I've done wrong. I thought it maybe earths. The guy from the company i got em from said earth one to the battery and one to the chassis. Well i earthed both to chassis as wire wasn't long enough to get back to neg on batt. Wen it didn't work, it tried extending the wire on one bulb to the neg on the batt to see if that worked, NOPE. The earths must be ok as the wen u take it off then recconnect, you can hear the levellers working Please offer advice if you got any.

Where did you guys earth yours to?

(The engine was running btw when I turned the lights on. )

Thanks

Ok after I found this and read it, I worked out that i has put the sockets into the ballasts the wrong way round http://www.fiestamk6.com/joomla/inde...mods&Itemid=53


the lights now come on, however one comes on and stays on. The other flickers, then goes off straight away. Tried the earth, even earthed the flickering one straight to the battery, and does the same. Anyone got any ideas?
