Done that before on my Premium X. The main point to look out for is the location for the camera wire to go inside the boot. My installer route the wire through the license plate light causing one of the clip to broke off and not getting a good seal.
Thus I reroute the wire myself through the Perodua Logo "White Colour Insert" by drilling it through. This method require the removal of the rear Chrome garnish and only applicable for camera with the small 4/5 pin connector.
