Help with the grey wire!

Ok i have to concept and urge to do this mod. I know exactly what to do and all the tools...but how do I get the clip out of the the 4x4 computer? I fiddled with that mf'er for a hr and no luck. Am I missing something or am I just a idiot?

 

what clip? all you need to do is cut the wire and ground it

 

I couldnt get to the wire without it out. I think the step by step I read said to take it out

 

on the connecter there is i little tab in the middle. push this tab in and pull the connecter out. if it give you issues still, try pressing the tab and gently prying with a small screw driver.

 

I pressed the tab with a small flat head screw driver and eased down and it came out.
