I don't think most people are aware that as an owner/operator, or a fleet, can get a dtnaconnect.com login which lets you lookup schematics, repair procedures, etc for any Daimler family of vehicles (freightliner, western star, sterling, Thomas bus, etc) that you own. You just have to fill out the application on this link. From what I was reading they verify the info you submit against the warranty info on file, so if you bought your truck off some guy then I don't know how good your chances of getting access are.
