Agreed absolutely.You can plug one end in backwards which is a Very Bad Thing.

I don't think that is possible. Pin 1 comes to an IDC point nearer the end than pin 2, so must connect to the outside conductor on the ribbon cable. It doesn't matter which side of the plug or socket the cable comes, it always runs correctly. If you make your own cable, it is possible to connect wire 1 to pin 2, then 2 to 3 and so on, but it's difficult because the last wire wont fit properly.
