Quintin - I read the thread on the Xenon-HID upgrade with an H13 bulb (me: 2005 stock F150). However, the instructions I got from A Line Electronics are pathetic - and I did not fully understand the responses in this thread. Seems obvious that the high beam is now abandoned. On the A Line unit, though, there is a black wire and a red wire with narrow spade terminals on the end. I don't understand and A Line has not responded...black goes to ground and red to the low beam? The other connectors are obvious (to the ballast module for example). There is no visible igniter - so I assume it's integrated - though I do not see it in the cutaway view of the ballast housing.
