OK, how do you remove pcm electrical connectors on 2005 C6?

BlindSpot

ECMs use a locking lever type connector like this:

Think of the grey bar like an electrical throw switch. Move the grey bar over to the other side, the connector will rise off the mating connector. You put the new one on in reverse order. Start with the grey bar in the open position. Start the connector on the mate, and move the grey bar back into the locked position. It will draw the connector down into the fully seated position.
