Connect Fully Noded

In Fully Noded go to 'Settings' > 'Node Manager' > +, from there you will be automatically prompted to add a node:

    add a label
    add the rpc user: lightning
    add the rpc password is your Password_B
    add the onion address (also shown on the display as a QR and below), ensure you add the port at the end: 
    ${toraddress}:9080"

    ignore the macaroon and cert as that is for LND only

Thats it, Fully Noded will now automatically use those credentials for any lightning related functionality. 
You can only have one lightning node at a a time, to add a new one just overwrite the existing credentials.

In Fully Noded you will see lightning bolt zap buttons in a few places, tap them to see what they do.
