I just purchased an h1 hid conversion kit. I have read that i need to disable the drl module so that reduced voltage doesnt cause my hid's to not light up. I have also read that the drl uses some logic along with a resistor pack to place extra resistance on the ground wire. So if this is the case, I should be able to directly ground the his ballasts and hid's would function correctly. If anyone knows how to disable the drl's let me know, otherwise i will put a multimeter on the ground wire and see if the resistance decreases to ground when the headlight switch is on and if it does just ground the hid ballast ground wire directly to ground.

Also, If any of you have done this conversion, tell me, The bulbs on the 05 wrx are h1, the factory wiring goes through a plastic housing with an o-ring to keep the elements from the bulb. With a conversion kit, it would seem the hid bulb (requiring different wiring), would require some drilling of this plasic cover / seal. correct?
