i'm having trouble installing my HID lights

[pac4life81]

im having trouble figuring out what this cable is. im not sure where it goes i plugged everything together but i cant figure out where that cable belongs. I feel pretty stupid cuz i thought this was gonna be easy but its not. lol... is there anyone who can tell me where it belongs =)...id really appreciate the help =)... by the way its a xentec kit. oh and one more question howcome the hid light is slighty bigger than my OEM light? I ordered an H11 for 2008 altima thats correct right?

thats the wire that connects to the ballast and to your factory harness, H11 is the black piece that those prongs go into and thus fits into your factory harness which is an H11 plug.
