Yeah, I dunno why they didn't come that way until 07 on the trucks. My car is that way with no mod.
I just used a diode and jumped 85 (switched power) on the low beam relay to 85 (switched power) on the high beam relay. This gets around the short that'* created when you flip the high beams on.
I originally tried to just use wire, but it had to be a diode so power could only go one way.
