The cover then comes off with a little wiggle. You will see three covers with a 10 mm bolt holding them down and a cable connected to each. carefully remove the cable without braking the connector, unscrew the bolt and the cover lifts out the plugs are under the covers. They are deep down so you will need long plug socket to unscrew them.
