Windows 95 has no direct bearing on the wiring of a computer. Without more information, such as the motherboard model or form factor, it is impossible to help you.
A wiring diagram can be found at this website: http://www.abcccodes.com/95-isuzu-npr-wiring-diagram/ for the Isuzu NPR. The diagram can be downloaded as a PDF file.

There are a couple locations to find the wiring diagram. You can go to Cadillac forum/club sites like caddyinfo.com or you can get it from parts supplier website like autozone.

A power see wiring diagram, for your 1995 Chevrolet Blazer, can be obtained from most Chevrolet dealerships. The wiring diagram can also be found at most auto-parts stores.

You can't. What you can do is to install windows 95 on virtual machine, and try playing. Most likely it will not work either.
In a chiltons or a haynes book you can get at your local parts store.
Windows 95 cannot be installed from inside a newer version of Windows. You must boot from a disc to install it. Windows 95 isn't compatible with newer computers anyway, and virtually all software that will run on Windows 95 will run on XP, so its a wasted effort.
