Thus far i've had no heat issues even in ~14hrs of sustained use on a road trip. The projector lens itself is a big chunk of glass which absorbs and holds the large majority of the heat preventing any issues.
The only change that needs to be made to the wiring is the 4hi mod. http://www.gmt400.com/forum/showthread.php?122-4-Hi-Headlight-Mod The HID ballasts plug right into the low beam plugs (you may need to plug them in backwards depending on polarity).
I recently enabled the high beam shutters by simply splicing a male headlight connector onto the shutter wires from the projector and then connecting them to the high highbeam plugs. Very impressive how much more light they throw out with the shutter open.
