[Shotimes] pulling computer

[ROBERT SCHIRMER]

Guys

I am trying to pull my H3Z computer out of my 93, and replace it with a  D4U1
computer. My problem is that I can't get that old one out. Looking at the
depth of the pins on the D4U1, I believe I have pulled it about 3/4 way out,
but no amount of force I pull on it with will help the rest of the way. I have
enlisted the help of vise grips and all. Is this just a matter of wiggling it
and pulling? I noticed the back side of the D4U1 computer has a built in nut.
When I get this computer out, is the cable bundle held in place by a screw??
  Thanks in advance
