To find it:
1. Locate the PDC: It's a large black plastic box with many fuses and relays. Look near the battery, often on the inner fender well.
2. Open the PDC cover: You'll likely need a screwdriver to pry it open. There should be a diagram on the inside of the cover showing the fuse and relay positions.
3. Consult the diagram: Find the relay labeled "starter" or look for the amperage rating that should be relatively high (generally 30 amps or more) which is common for starter relays. Sometimes it might be listed as "start".
Important Note: Without a wiring diagram specific to your 1995 Dodge Ram 1500 van, pinpointing the exact location within the PDC is difficult. A wiring diagram in a repair manual (like a Haynes or Chilton manual) will provide the most accurate information. You can also sometimes find diagrams online if you search for your specific year, make, and model.
If you can't locate it using the PDC and diagram, it's best to consult a repair manual or a qualified mechanic to avoid damaging other components.
