There is a wiring harness that a member on here makes to run your hi/lo beams together, it wont overload anything as it pulls power from the battery aswell instead of all thru the headlight switch, member meangreen is who makes it and i believe he sells them for $25 iirc, he has a thread in the for sale section or you can pm him

os you can spend the extra money and buy his $95 headlight harness that is heavy duty, has 4-hi, and will allow you to safely and efficiently run HIDs...

I wouldn't own a GMT400 without this mod. Don't know why GM didn't do this from the factory.
You can't beat MeanGreen's stuff. Better quality than the ebay ones, & the instructions are written by an 'English-as-a-first-language' person!
