Looks like common +12v and individual grounds so it should be easy to connect.
3 amps is getting up there for the controller but I think it will be ok, maybe after running a few hours touch the mosfets to see if they get hot. You'll see a row of 7 like your last image.
You will need to use the external power supply as controller is only 12v, here's a drawing someone made so I could connect the dots, you can see how the ground from 20v power supply goes to a common ground on controller (use those ground pins above the DC ports). If you're unsure post a pic of how you think it should go.
The blue and grey wires in your controller would go to a separate Ground pin on a DC port, best to use 4-7 as they don't have the backup float port.
