How to install the Rear Chrome Beading & PVC Piping

Looking for advice or pictures showing exactly how to install the Rear Chrome Beading BD-28275 and the PVC Piping BD-18288 that goes under the chrome beading. Also how far up is the chrome beading from the rear deck as it attaches to the tack strip? I was going to start in the center and work my way outward. Then how to trim the PVC Piping at the ends.
