Connecting a laser power supply to a new drive board

Hello everybody
A number of years ago I built a lasersaur, but the driveboard has now packed up and I don't have the soldering skills to make another one so I have bought my self an Openbuilds Blackbox motion controller.

I have everything moving and homing again, but electrical stuff isn't my strong point and I need help connecting the laser power supply up the the Blackbox and chiller. I have drawn and attached a diagram which I hope explains what I want to do. Could somebody please tell me where each wire should go.
Thanks In advance
Aaron
