Hi!
Welcome to the community.
To retrofit the electric rear sunshade in your 2016 ATX, you'll need the following components:
-Sunshade motor assembly
-Sunshade cloth
-Wiring harness
-Switch
-Parcel shelf (if not already present)
-Brackets and hardware for installation
It is advisable to get these components from the same vehicle model to ensure compatibility and a successful retrofit. If you are getting the parts from a wrecker, make sure they are in good working condition.
It's recommended to consult a professional installer or mechanic for the retrofit process, as it can be complex and requires electrical wiring knowledge.
