In addition to premade connectors, MotorMite now stocks crimpers for Weather Pack and other GM terminal systems. (Will work with most "open barrel" connectors used in all cars) They also have a release tool for the Weather Pack terminals. Their release tool set has 2 small screw driver style tools and the tubular weather pack tool.
Lysle also has a release tool that is more GM specific.
I'll be writing this up in more detail over the next week. Keep an eye on the ECM section of the cave for more info.
