1. Consult the Owner's Manual:
* This is your best bet. The owner's manual should have a detailed fuse box diagram, specifying which fuse controls which circuit. If you don't have the original manual, you might be able to find a digital version online through sites like eBay, manualslib.com, or the Dodge website (though availability for a vehicle that old is unlikely).
2. Check the Fuse Box Itself:
* Inside the fuse box: Many fuse boxes have a diagram printed either on the inside of the cover or on a label affixed to the box itself. Common locations are under the dashboard on the driver's side, under the hood, or even in the cargo area (depending on the van's specific configuration).
* Look for markings: The fuses themselves may have small numbers or letters that correspond to a legend printed somewhere on the cover or nearby.
3. Online Resources:
* Online forums: Search online forums dedicated to Dodge vehicles or vans. Sites like DodgeTalk or other enthusiast forums might have members who have already posted diagrams or can provide assistance. Be sure to specify the exact model and engine of your 1992 Dodge Cargo Van (e.g., B150, B250, B350, engine size). This level of detail is crucial.
* Repair manuals: Websites selling online repair manuals (like Chilton or Haynes) often have diagrams included as part of their service information. While they are paid resources, they can be very helpful.
* eBay or other used parts sites: You might find a scanned copy of a fuse box diagram included in the photos of a used owner's manual being sold.
4. Local Auto Parts Store:
* AutoZone, Advance Auto Parts, Napa, etc.: These stores often have access to repair information and may be able to print out a fuse diagram for you (they may need your vehicle's year, make, model, and engine). They might also have a digital database they can access.
Important Considerations:
* Multiple fuse boxes: Your van might have more than one fuse box. One is typically under the hood and another inside the vehicle.
* Relay locations: Relays are also common components that control electrical circuits. Your diagram may include relays as well, and it is important to distinguish between fuses and relays.
* Year and Model Variations: Even within the 1992 Dodge Cargo Van lineup, there may be differences in fuse box layouts based on the specific model (B150, B250, B350), trim level, and optional equipment. Be precise when searching online.
By systematically checking these resources, you should be able to locate the fuse diagram for your 1992 Dodge Cargo Van. Remember that safety is paramount; always disconnect the negative battery terminal before working with the fuse box.
