Narrative:
Aircraft returned to gate for 'left reverser isln vai' message and 'reverser isln' light after starting right engine. After performing steps in MEL and after aircraft departure, I and another a&P were looking at the history of this item and found a note off the MEL to check a bulletin and after reading, found I pulled a wrong circuit breaker. I pulled the 'thrust reverser indication' when I was to pull the 'left engine thrust reverser ssl cont.' after I found out, I informed my lead a&P and called ZZZ maintenance control desk for B767 and B777 and informed them of my mistake.
