The main wire connector that goes through the firewall on the driver's side. How do I unhook/unplug it? I took off the two small nuts on the sides, but I still cant get it apart. I dont want to force it because it doesnt look like the sort of thing that I want to break.

 

if i remember correctly all of them i ever did had a screw in the center, but you'd see that. just wiggle it and pull, all i've unplugged came right off, more or less.

 

I took the one off the 92 Z I have and it had a bolt in the middle of the plug, it's hard to see and get at.
