Where can I get a wiring schematic for a '97 Freightliner chassis. BlueBird body but I am having trouble with power to modulator and can't find out where it should be coming from. I found the relay but need more info. This is a rebuilt trans and shifts way too soon if you let it shift automatically. Does the modulator have that much to do with shift points? I don't have any diagnostic stuff to check anything out. Thanks, ED
