Dodge Ram fog light wiring can be a complex task, but with the right information, it's manageable. The wiring process varies slightly depending on the model year and whether the truck came with factory-installed fog lights.

Locating the Fog Light Wiring

For most Dodge Ram models, the fog light wiring is located on the driver's side, near the front of the vehicle. Look for a wiring harness with a plug near the radiator support or behind the bumper. In some cases, there may be a 4-prong plug on the driver's side just behind the bumper.

Wiring Colors

While color codes can vary, typically:

  • The power wire is often red or pink
  • The ground wire is usually black
  • The trigger wire may be tan or light green

Always consult your vehicle's specific wiring diagram for accurate information.

Factory vs. Aftermarket Installation

Factory Installation

If your Dodge Ram came with factory fog lights:

  • The wiring harness should already be in place
  • You may need to install a relay in the fuse box at Fog Light Relay 2
  • Ensure the headlight switch has the fog light option

Aftermarket Installation

For trucks without factory fog lights:

  • You may need to run new wiring from the battery to the fog lights
  • Install a relay and a separate switch
  • Consider using the factory fog light plug if available, but be aware of potential computer issues due to different power draws

Wiring Process

1. Locate the fog light wiring harness

2. Identify the correct wires using a multimeter

3. Connect the power wire to the battery (with a fuse)

4. Ground the black wire to the vehicle's chassis

5. Connect the trigger wire to the switch

6. Install a relay if necessary

Tips and Warnings

  • Always disconnect the battery before working on electrical systems
  • Use a relay to handle the current load and protect the switch
  • Consider using a separate switch and relay to avoid computer issues with aftermarket lights
  • Some models allow fog lights to work with high beams after a computer modification, but this may not be legal in all areas

Remember, if you're not comfortable with electrical work, it's best to consult a professional to ensure safe and proper installation of your Dodge Ram fog lights.
