    Default HI-4 mod with HID's

    I have 8k HIDs in my 02 silverado 1500 right now. They flicker bad so I'm getting a relay. I've heard of a hi-4 mod without having to buy a kit. Does anybody know how to do this?

    I've heard of something about taking the ground off the battery and grounding it to the truck...

    All you need is a diode run between the high and low beam triggers in the under hood fuse box... I used 1N914 Diode.

    Here's a link to the write-up I used for my Avalanche... I think your underhood electrical center should be similar...
