Open the box and inspect the item. Verify what was received was what you ordered and that the item is free from physical damage or defect. Remove the old tail light. First thing you have to do is undo the mounting screws on the outside, if there's any. You'll have to open the trunk or any rear door or opening on the vehicle to access the back of the tail light.
The wiring harness must be disengaged from the assembly through its back. Once the wiring harness is out, you can now undo the mounting screws or nuts, whatever fastener is used. With no more screws or nuts holding it in place, you can push out the assembly from behind. Check if the tail light assembly you just removed is the same as the new one. See if they have the same components, design, and fasteners to ensure proper fitting.
Fix the new assembly into the tail light pocket. Once it's fitted into place, secure it with the screws or nuts. Plug in the wiring harness that you removed earlier. Switch on the tail lights to see if they work. If not, then some adjustments should be done to the newly installed tail light kit.Put back any cover, trim, or component that was removed to access the tail light assembly.
