Default pcm cover removal

Anyone know how, I squeeze both ends of the cover but it gets hung up in the middle. I need to get to the 10 pin for the tach wire. The center bolt seems to hold it in place but when unscrewed it just loosens the whole pcm !, Anyone ?

Install U doesn't tell about this "hold up" maybe 2002 specific ?, Help !

There is no need to tamper with the PCM to tap into the tach signal. The tach signal is present at pin G of connector C105 which is the middle connector in a group of three above the passenger-side wheel well. It is a white wire. Be aware that there are two white wires at connector C105 and make sure that you identify the correct one.
