Where are the relays located on a 2008 Dodge Ram?
The relays are housed in two engine-compartment fuse/relay boxes: the Integrated Power Module (IPM) on the driver's side of the engine bay and the Power Distribution Center (PDC) in the same area.
Identifying the two main relay boxes
Open the hood and look for two black plastic boxes with removable lids. The covers usually have a diagram showing which relays and fuses are inside. The IPM is typically mounted on the driver's side inner fender, while the PDC sits nearby in the engine bay and contains additional relays and fuses.
Inspecting the covers and diagrams
Both lids include a diagram that maps relay numbers to their functions. Use these diagrams to locate the exact relay you need to test or replace.
- Integrated Power Module (IPM) — driver’s side of the engine compartment, inside a black plastic box; contains high-current relays and main fuses for several essential systems.
- Power Distribution Center (PDC) — another under-hood fuse/relay box in the vicinity, with its own diagram on the lid showing the specific relay assignments.
Note: Exact locations can vary slightly by truck model and options. If you cannot locate the boxes, consult the owner’s manual or a factory service manual for the precise layout and the lid diagrams.
What to do if you’re diagnosing a relay
Before testing relays, disconnect the battery and use the diagram on the lid to identify which relay corresponds to the system you’re inspecting. A common approach is to swap with a known-good relay of the same type to test function, or use a multimeter to verify coil resistance and contact continuity. For precise instructions, refer to your RAM’s specific build sheet or service literature, as relay configurations can vary between Ram 1500, 2500, and 3500 models and depending on the engine.
Summary
On a 2008 Dodge Ram, look under the hood for two main relay boxes: the Integrated Power Module on the driver’s side and the Power Distribution Center nearby. The lids’ diagrams map each relay, helping you identify and service the correct component. Always exercise caution when working with automotive electrical systems and consult the manual for model-specific details.
