A photo of what you're looking at would help. If you're swapping the housing only you shouldn't have to swap any harnesses (unless one is bundled with the new housing and you want to keep it).

Undo the 2 x screws. Whole housing slides out / unclips towards the rear of the car.

Then you should be able to remove the bulb holders and bulbs from the original housing. The wire harness could be snipped loose if it's tied to it.

The other end of the tail light harness goes through the metal body structure and into the inner trunk area where it connects to the main vehicle harness behind the plastic inner panels on either side of the trunk. It's pretty simple to get in there, but is a bit involved. This is why I'd say keep your original harness if the lights themselves are working fine.
Ok so I love this answer. The part I have is the whole part going down to the plug. On the part that I'm replacing I'm able to easily grab the bulb out but the other part really doesn't like me (I can't get it out.) So in your opinion I should cut those wires on the troubled part and put the new one in rather than plugging the new part all the way to the bottom? ( I still don't know how to access the plug )

This issue probably warrants its own thread as it's OT from the original post.

I wouldn't cut any wires. If you can't free the harness from the housing I would swap the harness as well. You will need to gain access to the connection behind the interior panels in the trunk behind the tail light. If you're not comfortable removing interior plastics I would think it should be a relatively inexpensive process to have the dealer do it for you.
 
I am also trying to swap out a tail light on a 2017 CX-5 GT. Any help in what steps are to remove the panel in the trunk cargo area? I need to swap the entire unit as the housing is cracked and is a LED set

Thanks

I'm confused. You just want to swap out the main (outer) unit, right? You don't have to remove and panels to do that. Open the hatch and there's a little pry-off panel, about 3x1 inches, on the inside edge of the cluster. Unclip that and undo the two screws there, then just pull the cluster towards you to unclip it. Done.

Thanks for the info on removing the liftgate taillight assembly and the LED bulb info. Ill let you know what solution I end up with as I cant see driving around with these subpar taillights. I dont mind the taillights not being LED but I do mind that such a small portion of the taillight lights up. If you compare the CX-5 (non-GT) to any other modern car you will see how small and inadequate the taillights are.
Did you ever find out if the liftgate lights have the wiring in place to plug and play the GT LED tailgate lights?
