Thread: Sport Trac Carputer with factory HU

I am trying to set up my carputer. I'm gonna have to make it work with the pieces that I already have. Here's what I got:
Sport Trac factory HU - Pioneer with in-dash 6 disk changer...
like this:

There is an available input in the back of the stereo.
like this:

This is a 20 pin female connector.
Question 1-3 = Do they have an adapter for this input that I could buy, or is this even an input? Do I need to splice into one of the other plugs?
If someone had some type of schematic for this particular stereo they would be my idol.

The other portions that I have that I want to make work are as follows:
I have a dell laptop. I wanted to use this in conjunction with a docking station that I obtained for it. I was thinking I could mount the docking station somewhere out of the way, under the rear seats maybe, and that way I could easily remove the computer. I will be getting a secondary touch screen monitor to mount up front somewhere.....
Questions 4-5 = Has anyone done this sort of thing (using a laptop and docking station), and if so in a Sport Trac (or Explorer)? Also, any preferences on where to mount the puter and touch screen?

I welcome all suggestions/comments.
Thanks!!
