  1. Flickering HIDs? The "problem" is with the car's computer not recognizing the relatively low load your HID relay is drawing compared to the conventional incandescent bulb. These are VERY smart, highly engineered cars. The turn signals and headlights each have separate power circuits, but share a common ground circuit. If you have wired your HID relay ground wire for the original headlight power (now the "on/off signal") circuit to the fender or other grounded part, then when the turn signal is also turned "on" the computer measures only the current drawn by the turn signal through the standard, monitored ground circuit and is not able to account for the reduced load expected to be pulled by the two circuits. This causes it to try to figure out what is going on by modulating the pulse width of power to the headlight circuit....to the point of providing too little current to keep your HID relay energized. When it opens, even momentarily, the spark between the electrodes of your HID bulb collapses and your ballast may or may not be able to re-light it before the next collapse. Thus, the "problem" does relate to your ground connection, but probably not the way you are surmising. You will either need to re-wire your relay to the original ground circuit, add a heat producing, power consuming resistor to the power side of the circuit, or insert an capacitor to supply electricity to the relay coil when the car computer does its thing (described above). The latter is the easiest and is available at Radio Shack for a couple bucks. For example, part number 272-1030, a 35v 470uf electrolytic capacitor. Bend the leads and insert them into the relay socket where the relay prongs are inserted, positive to positive, negative to negative, the capacitor should be marked for polarity, or the longer of the two leads will be the positive one, as shown in the attached photo.
