Quoting from the instruction Guide: 'The ProModule simply sits under the base of your CD32 unit and is joined at the rear of the case with the block connector supplied. After detaching the panel which covers the expansion port, place the CD32 on top of the ProModule casing and push the connector firmly into place, this will lock the two units togather. If you have the FMV cartridge installed, you will notice that the lock connector will accommodate for this as well.'
