Narrative:

On returning to work after my days off; I was notified that during a internal quality assurance (qa) audit the #2 eng hydraulic pump depressurization valve connector was found disconnected with no related documentation. After reviewing my action [for] february 2010; I recalled working the item on a B777-200 aircraft on the above date. While accomplishing this job (removal of the#1 igniter boss); I had a difficult time loosening the boss. Some heavier than normal tool was required to break to boss loose. The use of these tools came in the vicinity of the hydraulic pump connector and wiring. In anticipation of the possible slipping of the tool and damage to the connector or wiring; I decided to remove the connector precautionary. After removing the boss there was some delay obtaining the parts to complete the job; this lead to a job turnover at end of shift. Several write-ups were made regarding the job; however the removal of the hydraulic pump connector was not included.
