Hook up all three LCDs so that the first wire in each is hooked together, the 2nd wire is hooked together and so on. The following picture shows the wire numbers.

[1,2,3,4,5,6,7] [1,2,3,4,5,6,7] [1,2,3,4,5,6,7]

In the end this is how the wire order should look:
[1,1,1] [2,2,2] [3,3,3] [4,4,4] etc..
Use any method to achieve this result, but keep it small.

You are very quick to criticize. First off my original idea was to use array to send a spark to the indicated wire. So you know, INSL does not block BRAY.

You sir are no less of a "retard" than I am.

That would be my first option, but I need to reserve wifi for the rest of the save. I will resort to wifi if I have to.

Actually each wire needs its own separate channel (You could not have know this, I did not provide this information).

Anyway, I think I found a solution.

So you know, I am trying to make one number matrix work for three independent LCD screens (which is why it would require separate wifi channels).

EDIT:
In reply to Dragonfree97

Yes, now you see why I wish to refrain from using wifi.
