I've been having intermittent problems with the Internet connection of my HP Envy, which has an Atheros Wifi card. Some googling indicates that this is a fairly common problem with these laptops.
I contacted HP, and after an attempt at a software fix, they asked me to try to reseat the card before sending it in for replacement. They referred me to this document, which describes how to take it apart:

The diagram
When I got as far as the Wifi card itself, I observed the following diagram in the document (page 60 of the document):
Inside the machine
However, what I actually see inside the machine is this:
Unfortunately, I already disconnected the wires before taking a picture.
As you can see, the numbers and colors in the diagram don't match reality. What's more, the numbers and colors of the wires don't match the numbers and colors of the terminals. (The number on the black wire is 1, and the number on the white wire is 2, but the card shows white 1, black 2.)
I'm wondering a couple of things:
Do I just trust the numbers of the wires and hook them to the matching numbered terminals on the card? I think that's how they were connected originally, although since I didn't photograph them while connected I'm not 100% certain about this.
What would be the consequence of hooking them up wrong? (I'm wondering if that could possibly account for the connectivity problems I was having before?)
P.S.: I can definitely call HP support about this, but I was very curious to get an opinion from knowledgeable people on this site who I know aren't reading from a script.
