Hey guys! Just wondering if someone might have some insights into my issues:
I have a Type 4294-CTO X220T
1) I dissassembled the Keyboard and Palm-rest assembly to take a look at the mSATA / mPCI-E area today. I have a 3x3 Centrino card, but only 2 of the 3 connectors are connected. There are 4 antenna wires black, grey, red, blue. Only the Black/Grey ones are connected. Can I just connect one of the other two in order to get 3x3? I DID order a 3x3 screen!
2) Since I have 4 antennas does that mean I have a WWAN configuration, therefore I cannot use a mSATA SSD?
Here is my system configuration:

You might want to have a read of this thread. As far as your antennas go, what colors are the ones that aren't being used?

Hmm... well that helps but I think this means that my antenna setup is 2x2 instead of 3x3 because I do not have a white cable. This is kind of disappointing because I did order the 3x3.
Can I just use one of the WWAN red/blue antennas for the 3rd WLAN connector?

I have the same issue with my x220. so far support has not been helpful. I even had one tech ask me why it matters. aside from not getting what i paid for the 3rd anntena allow for higher wireless speed. his response was "oh"
yeah thanks lenovo support. anyway they could not find a part number for the MIMO antenna, but I'm still looking. its got to exist somewhere, right?. If i can get the part number and its not to expense I'll just order it and install it.
