How do you change the tail light assembly on 2004 Yukon Denali?

I bought new lights and want to do the change myself.|||open the rear door/hatch ,you will find 2 screws holding the light to the body,remove them swing light out to 90 degrees pull outward,unplug bulbs,noting which one goes where ,install new lamp fixture ,do one side at a time so you%26#039;ll have a model to go by.
