On my GMT900, they're both grounded to a chassis brace bolt as described over here. I extended the ground leads on the harness to do this.

What kind of HID's are you guys running? I had had 2 HID's (the first set i sold to my coworker for his silverado) and ive never had any problems with them and they didnt require hooking it up to the alternator or even the battery. the factory headlight harness just plugged into the ballasts and the HID bulbs went connected to the ballasts. No flickering ever. No dimming. (even when all the windows are rolled up and i keep holding up all four switches) No problems!

supposadly the relay it came with (not pictured) is so i dont have to disable the auto on, which is why it need to be connected to a pos battery source
