There are two types of ballasts. One type, they are referred to as "digital" will not work without the relay or capacitor. The other type of ballast is a "canbus" which from my research is "smart" ballast. It gives the proper resistance to make the headlights work, but the DRLs cause issues without a cap.
I personally wouldnt install HIDs without relays because of what the relays do. Your factory wiring to your headlights are designed to pass a certain amount of current. HIDs generally run on a higher current and this could mess up your factory wiring.
If you buy from Steve (the site sponsor) he only sells the Canbus style ballast, and if you specify that you have a nox or terrain he will include the proper stuff to make it all work right.
I bought from a more expensive other vendor and got the crap "digital" ballasts. They worked for all of 1 day, but when they did work, the 4300k looked great.
Have a look on the forum link and you will see I have installed both the HID kits from Steve in our Terrain. One set in the low beam and the other set in the fog lights.
Xtreme Digital Xenon HID Conversion kits due not have a built in canbus, rather if you order from Steve he makes sure you receive the canbus fix (capacitor) this just clips inline with the ballast.
His kits come with relays.
Do not have to use the relays and wiring with these.I have done both sets in our Terrain with NO relay wiring.Just the ballast and the canbus fix.That is it no wiring of relays.
You unplug the stock headlight
remove the light bulb
plug the canbus (capacitor) into the ballast
clip the ballast to the factory wiring
install HID bulb
clip other end of ballast to HID bulb
DONE call it a day.
NO WIRING is needed.
I have installed with the relays and without.The lights work just fine without the relays.

Here is were the relay wiring is that came from my kit from STEVE.
