How do I release the connectors in the ecu plugs? I have a kit with the tools but can't get them to release them

Still not working.   Just rewired the wire connector on floor board under front of engine. Still no spark. Next step is to clean connectors on the 2 ecu plugs. I cant release them from plug. 

Bike was flooded in tropical storm.  Replaced ecu and coil. Motor turns over but no spark have 12volts on one wire of coil. How much voltage should be on other small wire? Crank position sensor is about 200ohms. . Cleaned plug with sandpaper. Want a wiring diagram to check voltage at ecu. I have update. The blue wire going to coil has no voltage when turning it over. The white with black stripe has 12vdc when key is turned to on position.also, how do I clean the connectors on ecu? I dont see how I can get a  screwdriver in there  to release them. Found a schematic.i still need to clean connectors though
