I bought one of those $30 code scanners and when one of the terminals on it worked loose I gave up on it and used a 10-cent paperclip along with the check engine light on my brother's 93 Escort (my 95 Contour also blinks the check engine light, my 88 Mustang would too except that it doesn't have a check engine light, never bothered to install it)
For $30, the full version of the manual on that website is a heck
of a lot more useful than the manual that comes with the $30 code
scanner.
