Narrative:

Accomplished the maintenance procedures manual 79-02. I disconnected, by mistake, the wrong connector. Was engine oil filter differential pressure instead of engine oil pressure transmitter. So the plane returned back to the gate. I made contact with ZZZ1 technician. They told me to rechk the cannon. I did -- it was the wrong connector.
