Large fold-out wiring diagrams for the heavy-duty models that the index lists by MD number rather than T number, such as the 6500 V/A, 7500 and 9500 series and the diesel models. The sheets are image-only and their captions are too small to read, so individual diagrams are not identified here; use the index on page 2 to match a series to its MD number.

What this section covers

  • MD-numbered fold-out diagrams
