Ok seen all the pics but nothing that showed me how to get there. So took apart and restarted. Here are the steps

This is the metal piece that comes with new skid plate. The 3 holes in blue you will use to attach your existing plastic cover to.

This is the plastic cover that is on your car already. You will need to take it off and re-use it.

Drop the plastic cover piece on the metal bracket so the 2 big side cut outs are facing up and the holes align with the 3 holes in blue. The 2 holes in yellow are going to be where you bolt the metal piece to the lc.

Take 2 of the extra bolts from when you removed the orginal skid plate and use them to attach the metal piece to the frame (where the yellow lines are represents where the bolt holes are on the frame)
Once installed your plastic trim pieces should have a large side cut out on each side facing up (there is a small cut out on each side that will face down- not marked in pic) and the center cut out facing down- marked in blue.
Now your black metal piece and trim are done. Install skid plate (so much easier) and all set.
Still have no idea why there were zero directions or pics for the black piece. Ugh.
Hope this helps.
