@ 05 Bee, I'd be worried about the 9005 bulb. It's a 65W bulb compared to the 9150 which is a 45W bulb in a much smaller plastic housing. Each 9005 is drawing 1.5 MORE amps on the stock wiring. Let us know how it works out.
In regards to the low beams in the quad headlamp, here is a link:
I don't believe the adapter will fit in the headlight assembly, which means you have to modify the bulb socket:
They also have something called "The Brite Box" which will allow you to have your highs, lows, and fogs on all at once. I only see Dodge Ram up to 2008.
I'm going to see if I can get my hands on a pair of H9's locally.
