Anybody please give me advise on how to get the O2 sensor(front) clip to come apart. I have it unscrewed etc, but I can't seem to get the sensor snap thing to pull out of the recieving end. Thanks. Quick response would be much appreciated. Is there a way that the clip explodes or comes apart from each other? Stupid question but I need to know.

 

There should be a red tab on the connector housing, pull that red tab away from the connector and the connector will seperate
