Might try going to RadioShack and getting a molex tool.
They work pretty good for removing GM weatherpak terminals
Only about $6 and look like a hollow screwdriver with no tip.
Push the terminal into the connector as far as it will easily go, push the tool
over the pin (on the pin side)and it will force the retaining tabs away from the connector.
with a pair of needle nose pliers, remove the terminal from the wire side of the connector
