Well, its pretty simple. Keep in mind you do this at your own risk! So back up your files! This is only for owners of the fs2crew 744 pmdg version and of course the pmdg 744/744F
1.) Rename your 744F panel folder to panel.old
2.) Copy for 744 panel to your 744F folder
3.) Copy this over the vc section in your new 744F panel folder's cfg file

4.) Add this line under the window.2 section (overhead panel). This will give functionality for the cargo doors.

5.) Give it a test run! It worked well for me. You will have the 744 main panel and the 744F v/c. I don't about actual functionality in the v/c because I mainly fly in the 2d panel. But it still looks great!
