Yamaha m7cl help with ribbon cable question...

Hey gang, im currently working on an m7, replacing fader banks etc, and ive removed the stereo in/out module. The ribbon cable is grey and has bare ends showing now that ive removed it from the connector... This connector raised up", like a locking mechanism , but it released so quickly i almost felt that it broke? Do these ends just set back in the connector holes, and re snap the lock mechanism back down? Im hoping whenthe new card comes, it'll have some sort of instructions cause the online sources are shit... No youtube, nothing in the online service manual... Hoping you can help... Ill attach photos.
