If you are looking at the MiniPAC I wouldn't use Molex connectors for the modular control panel. It would be much easier to use IDC DB connectors. The DB connectors come in many sizes such as 9, 15, 25, 37 pin configurations. The nice part if this is that you take a piece of ribbon cable and put a double row IDC connector on one end and an IDC DB connector on the other end. No little pins to crimp!

To wire from the DB connector to the control panel you just get another IDC DB connector and another piece of ribbon cable. Separate all of the wires, route them to your controls, cut the wires to length and then attach the quick disconnects.
The only issue here is attaching the quick disconnects. Ribbon cable is normally 28 guage wire, sometimes 26 guage. This is a bit smaller than the quick disconnects like. Sometimes folding the wire over before placing it in the quick disconnect is enough to solve to problem. There are smaller quick disconnects available, they are just much harder to find.
