Here is a simple reaaaly simple wiring diag for one rgb led and the ledwiz:
the rbg drive from ggg comes equiped with a 4wire cable attached to the driver itself:
split the wires carefully
run the 3 grey wires to 3 different ports on the wiz
run the grey/red wire to the 5v output
for more led 5v power use a terminal strip and piggy bank the connections
