You don't. Everything seems to be tied to some sort of money exchange and property rights issue
on the internet these days. Not being a wise guy here, it is just the way most exchanges ideas and materials have developed as the internet has evolved. The best you can hope for is that someone on one of the International Truck websites has one and is willing to scan you a copy. Once in a very great while, you will get lucky and find a site, such as Autozone, who has done the legwork to make everyone who is attached to the rights of diagrams happy, who offer on their site access to a wide range of wiring diagrams and other tech info. But finding info is still a giant pain today and sometimes, even worse than it used to be.
