To Mark Bell, K3MSB. First of all, do have a factory power supply? The plugs you will need are 1 plug for J203-8pin octal female. For the other end to the PS you need an 8pin octal male. For the control connectors you will need a 9pin octal female for the Xmtter end and a 9pin male plug for the power supply end. I hope this helps you. Merl Chavis W7XM
