Learn about Dodge Ram 4500 / 5500 Chassis Cab 2018-2024 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.

The Dodge Ram 4500 and 5500 Chassis Cab (2018-2024) are heavy-duty trucks designed for commercial use and customization. These trucks come in a chassis cab body style, which allows businesses to install specialized bodies, such as flatbeds, tow trucks, or utility boxes, depending on specific needs. Both models are known for their rugged build, high towing capacity, and powerful engine options, including a 6.4L HEMI V8 and a 6.7L Cummins Turbo Diesel engine.

The electrical system plays a critical role in the vehicle’s functionality, and it is essential for owners to understand the fuse box and relay locations for proper maintenance. The fuse box, located under the hood, controls crucial systems like the headlights, HVAC, and towing electrics. Relays, which are typically found near the fuse box, regulate high-current systems such as the starter motor and fuel pump. Ensuring that the fuses and relays are in good condition is vital for the smooth operation of the truck’s electrical components, especially when handling demanding jobs.

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.
