    One of my trucks is a 1988 Freightliner FLC 120 and I need a wiring diagram to attempt to straighten up and trace some wires under the dash. I originally was attempting to fix a low pressure alarm that wouldn't go stop ringing and found that the fellow who owned it before me added his own little touches to a few things, and I'm trying to figure just what was done. There is a basic diagram on the cover in front of the shifter, but there are many more numbered wires under the dash, than shown on the diagram. So if anyone has a manual they could copy one out of or a link to one, it would be a lifesaver.
