Expansion card installation

[kk6ou]

I purchased an expansion board for my F4v3. I went to install it and found that the connector on the back of the Expansion board is smaller than the connector on the F4v3. It isn't keyed so I'm at a loss of how to install it. Has anyone installed one of these that can give me some advice?
Thanks,

Disregard.  I figured it out.  The connector is smaller but has 40 pins as the F4v3 has.  Just not keyed.
