* Owner's Manual: The most reliable source. Check the section on fuses and circuits. It should have diagrams for both the underhood fuse box and the interior fuse panel (if it has one).
* Repair Manual: A Haynes or Chilton repair manual specific to your 1996 Dodge Ram Van will contain detailed diagrams and explanations of the fuse boxes.
* Online Automotive Repair Databases: Sites like AllDataDIY, Mitchell1, and others (often subscription-based) provide detailed repair information including fuse box diagrams. These are usually more comprehensive than what you'd find in a Haynes manual.
* Dodge Forums: Online forums dedicated to Dodge Ram vans (like the ones found on sites like DodgeForum.com or others) often have members who can help you find the diagram, or even someone who has scanned a copy from their manual to share. Be aware that the information may not be as reliable as official sources.
Important Note: When searching online, be very specific in your search. Include the year (1996), the make (Dodge), the model (Ram Van), and whether it's a 1500, 2500, or 3500 series (this affects the exact configuration). The engine size might also be relevant.
