Harness For Aftermarket Xenon Kit?

[babaquazi]

hey guys,

Looking to upgrade my stock halogen bulbs with a HID xenon kit off ebay, specifically this kit:

http://www.ebay.com.au/itm/260552366719?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

In the item description it said, "*Certain cars may require a relay harness and or canceller(sold separately)." My question is will i need this relay harness/canceller?

Cheers in advance!

For our cars, it's fully ready for plug and play unless you want to mount the ballasts further away than the provided leads.
