that is a step by step tutorial... my first time took me about an hour to remove the headlight from the car to change the bulb... today I can do it in less than 15 minutes... its all trial and error... do it on a day that you have allot of time to play around. I always suggest buying whatever LED/HID bulbs you plan on installing at once and just do it all in one day. I did it the opposite way and had to remove my bumper a hundred times.
remove intake and remove plastic covering on the fender, high and low is not accessible, unbolt the fuse box( 3 bolts, one down at the base)
and bend your arm to get to it lol the fuse side is harder. by doing this you can change the triangle, highs and lows
