HID headlamps. Good retrofit for 95 "Grand" Caravan, or electrical conflagration waiting to happen?

I am in possesion (legally) of a pair of 2003 Maxima and 2005 Volvo HID lamp sets.  I have been toying with the idea of installing them into my 95 Dodge Caravan,  but have no desire to become an electrical fire statistic.  Any ideas or suggestions as to electrical load or safety requirements needed?  I'm quite handy at kluging stuff together, but the kilovolt output at the HID transformers has given me pause.  My main concern is how to take the existing lamp wiring and making it work with the HID low volt input.  Your suggestions would be appreciated.  Thanks.
