I installed a set of HID's in a 03 trailblazer. Each ballast is wired to a relay and power is fused and connected to the battery . I'm using the power and ground from each low beam to trigger each relay . Everything works fine except when you unlock the doors . It wants to turn the headlights on and I'm assuming that there isn't enough power to turn the ballasts on. The relays start buzzing until you turn the key on . How do I get around this feature ?

85 - Fused Switched IGN
86 - GROUND
87 - One side of the cut low beam trigger
30 - Other side of the cut low beam trigger
87a - Not used
Wire in two relays ( one for each side ) and this configuration will separate the low beam wire when the IGN is in the OFF position and will reconnect the low beam wire when the IGN is turned ON.

Cool Ill have to give it a try . Would I need to have 2 relays per side then ? I wired 1 relay per side to basically give the HID's 12V right from the battery .

86-Power from low beam

85- ground from low beam

30-Fused 12V from battery

87- 12V to HID ballast .
