just looked at the wiring diagram and drl is just tapped into low beam wires.

and looks to me is very easy task.

green/red out from drl relay is drl tapped into low beam relay output side.
make sure to cut green/red, not the output wire which splits into green/orange(driver side) and green/white(passenger side).
then grab green/red that has been cut, tap into high beam relay output wire, this wire splits into green/black(driver side) and green/orange(passenger side).
if you don't know how to use multimeter, don't just go ahead and cut everything.

i am just saying based on wiring diagram, i was considering doing this to my car, so i will let you know tomorrow or early next week.
