As far as I can tell, it's the three that are wrapped together which you need. The other two are for the WWAN antenna.
From left to right in your pic, it should be WHITE, GREY, BLACK.
However as str said above, if Windows says it's not turned on, that has nothing to do with the antenna and is simply that windows either cannot see the WiFi card, it's disabled in Windows networking, or it's physically switched off.
