First, the outer plate only goes on 3 of the 6 ways so the splines engage. There are arrow to go by on the plate and hub. The ones on the hub are in the dots so are hard to see. Either way, put it on so the splines engage.
Second, completely loosen the cable at the handlebar lever.
While pushing the actuator on the top of the case over with your finger against the return spring tension, screw the adjuster in the center of the pressure plate until the arrows line up.
After all that, adjust at the bars for a little slack. Done
And welcome to BHQ
