TITANIUMBOND

Hello, First post on this Forum! It has been killing me on my 1997 Subaru outback to get the pin connections out of the baby blue B84 connector. I am trying to ground out Pin #81 to remove the CEL for the egr valve. The previous owner swapped the 2.5 for a 2.2. They changed the original automatic transmission to a 5 speed, so I am getting the CEL for the EGR because originally the car had a EGR valve but the new 2.2 does not have an EGR. So after hours of research I found if you ground out Pin 81 at the ECU it will tell the ECU that the car is a manual and does not require an EGR. Here in lies the problem, I for the life of me can not get the pins to release to move them! Could some one please let me know the secret to releasing the pins! I have stuck tiny screwdrivers in every hole and cant get one to release, there is not wire retainers to release. If you look at the pic below you can see what connector I am trying to work with. Thanks! connector.pdf
