Narrative:
Myself and another technician were given the task to replace the left wing overwing emergency slide pack. We accomplished the task and signed the proper documents and logbook. When the aircraft went into a heavy maintenance check; it was discovered that the slide deployment lanyard was not connected to the attach point rendering the slide pack useless. Myself and the other technician are new to the station and only worked together a few times. I believe there was miscom between ourselves in carrying out the maintenance manual steps in the installation of the slide. Also working in a dark environment (nighttime) we didn't detect the error. Communication between 2 workers is essential in doing a task and we failed at that. Double-checking the work performed is also required in aircraft maintenance.
