The diagram for the cab does not have anything shown for the terminal to the black and black/white wires. What do these wires do? Where do they go to under the dash?

I´d say that these wires have been put in by a previous owner. The wires in Fransiscos Diagrams are Factory. I have found a few things missing in the diagram but haven´t had time to change them or let Fransisco know.
