The t444e fuel injection is controlled electronically so there is no screw to adjust to turn the engine up. If you have two smaller wiring plugs going into each of your valve cover gaskets, then the leads for the glow plugs are the first and last pins, the ones on the outside edges. If it only has one big plug, I'm not sure which pins they are but you could take the valve covers off and test directly from the tops of the plugs to a good ground source. Resistance should be less than 1 ohm. To get manuals, I would suggest to look around on ebay or something like that. I found a good engine/powertrain manual for my F-250 powerstroke off ebay.
