Learn about Dodge P-Series 1965-1974 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Dodge P-Series (1965-1974) is a versatile lineup of medium-duty trucks designed for commercial and recreational use. Available in a variety of body styles, including vans, step vans, and chassis cabs, the P-Series is commonly used for delivery services and as motorhome conversions. These vehicles feature durable body construction and powerful engines, making them popular choices for work-related tasks and heavy-duty transport.
In the P-Series, the electrical system plays a crucial role in ensuring that everything from the lighting to the ignition functions smoothly. The fuse box, typically located under the dashboard or in the engine compartment, protects the vehicle’s electrical circuits from overloading. The relays, which are also located near the fuse box, help manage high-power electrical loads, such as the starter motor, fuel pump, and headlights. Regular maintenance of the fuse box and relays is essential to avoid electrical failures, ensuring that the P-Series trucks remain reliable over time, especially in demanding commercial operations. Understanding these components is key to maintaining the longevity and functionality of the vehicle’s electrical systems.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
