I am a little confused by what you mean " I would recommend picking a group of three outputs and wire them in the standard RGB order, using the lowest number in the group as Red and the highest number as Blue."
I believe he means for example
Wiz Output 1- Red (LED 1)
Wiz Output 2- Green (LED 1)
Wiz Output 3- Blue (LED 1)
Wiz Output 4- Red (LED 2)
Wiz Output 5- Green (LED 2)
Wiz Output 6- Blue (LED 2)
Wiz Output 7- Red (LED 3)
Wiz Output 8- Green (LED 3)
Wiz Output 9- Blue (LED 3)
..etc
Probably easier to configure that way
