there is 4 panels around the work station (only 3 or them open atm) you need a wrench, hold it down on a pannle to open, now this is important TURN OFF THE POWER to all the work station systems only utilities can be on during installation and then just hold the module and plug it in, done. Every module but radar modules go in to the work station panels, there placement does not seem to matter atm so you can just add them to any panel.
