Need Help finding something

Hey all,

I have a 93-94 ram wagon with a 5.9L magnum in it and im trying to find the wiring schematic for the interior and exterior of the van. i found the link on Factory Chrysler Parts but the wiring shows it going through the roof of the van but the wires go along the vans floor instead of what it shows in the schematic. Can anyone help me out? Thanks.
The van has crank windows no power mirrors and a rear defroster if that helps. Thank you.
