tino, you do not say which model Ecosport you have .Are you in the UK? Our 2018 Titanium does not have a reflective bumper. Most times on modern cars the 'bumper' is held in place by plastic scrivets. Usually these are one off use so you would need new to be sure. If you can identify the type buy from somewhere like Ebay, the last time I did anything of this nature the Honda scrivets were stupid prices. eg £2 each and for example the front bumper needed many.. Off Ebay they usually come in a pack . As to the camera it is between the two number plate lights under the chrome finisher above the number plate. The wiring for the electrics in the door pass through on the same side as the hinges midway between the two in the large black connector.
Reading your post it might be you want to fit a camera yourself, good luck. I believe you can buy a 'radio' type that considerably cuts down on wiring. It might be of course that Fords like many manufacturers have one off looms and therefore the wiring is already there. Whatever good luck in your quest.
