f150 wiring harness

I am trying to figure out which wiring harness I need to install my sons radio into his 2007 F150.  The kits from Metra,  scosche and American International do not match up to what is in the vehicle.  I would really appreciate any input you can provide.  The stock radio has the 1/8" jack on top of the dash for the aux input.  Please see the attached photos for clarification

I am including two links that will provide larger photos that will show that the wire harnesses on the factory vehicle do not match any of the wire harnesses from the list above.  Please advise.

Back of the radio.

Some of the wiring that goes to the 1/8" input and a warning light that is right above the radio

First off thanks for the speedy reply!    I believe I now see what you are saying.  I need both of these to handle the connections.  Correct?

Sorry to sound stupid here but I want to make sure I get this right.

The AUX plug only seems to have two wires coming out of the back of it. https://images......com/images/274313/big/met-705520aux.jpg

However, the AUX radio plug has quite a few more than that.  Do I need to worry about the wiring for the passanger airbag light?  That is the second picture I posted.  The way it looked the wiring for that light was integrated into the the aux input for the radio and plugged into the back of the radio.  or Is the passanger airbag light wiring independant of the radio and will still work?

The second picture is of the back of the aribag light.  The reason I am asking this is that those four wires are somehow tied in with the AUX plug and then plug into the secondary plug on the radio.  From the picture on the Metra Website the AUX plug only has the RCA hookups for the AUX plug on the truck and no other wires.  That is why I am confused and concerned.

After work today I will take a detailed picture of the wiring as a whole so you can see how everything is attached.  Again I am sorry if I am making this harder than it should be.

I told you you guys I was not totally sure what I was talking about.  Anyways I pulled the panels back off and noticed that the wire harnesses just seem to share the same path.  No clue whether or not they both actually go to the radio or not. 

This is my new question after looking at the 16-pin connector (secondary plug) that goes into the radio.  The Metra AUX only has the RCA's attached.  So, what do all of the other wires do?  I cannot imagine that Ford would have the wires going into the radio for no reason.  What am I missing here?

Here is the pic.  It did not work on the last post.
