It looks like you pretty much got this handled but i was gonna say i know, (or pretty dang sure) tunaslayer did HID's in his Hella's so he'd know what to do. But sounds like you got it figured out
i posted on his wall to see if he for sure did it and im gonna see if he has a write up on it or somethin jus so 100 percent sure on how to do it
tuna has different ones then me i think? mine are metal so i may be heatin em up withe the torch and bendin em lol
