The 1998 Dodge Ram headlight switch can be upgraded to the newer turn-style switch from later models. This conversion improves functionality and aesthetics. Here's how to perform the upgrade:

Compatibility

The newer turn-style headlight switch from 1998.5-2002 Dodge Ram models is compatible with the 1998 Ram. However, some wiring modifications are required for proper installation and function.

Parts Needed

  • 1998.5-2002 Dodge Ram headlight switch
  • Matching wiring pigtail for the new switch
  • 1998.5-2002 dash bezel (optional for improved fit)

Wiring Conversion

The wiring conversion is crucial for proper function:

  • Remove the old pull-style switch
  • Connect the new switch pigtail to the existing 1998 harness
  • Match wires based on function, not necessarily color
  • Ensure proper grounding connections

Important: Pay attention to the numbered pins on the new switch for correct wiring.

Installation Steps

1. Remove the old headlight switch and dash bezel

2. Install the new dash bezel if upgrading

3. Connect the new switch pigtail to the existing harness

4. Mount the new switch in the dash

5. Secure all connections and test functionality

Dash Bezel Considerations

If using the newer dash bezel:

  • Drill out mounting points for the 12V power port
  • Use ABS plastic glue or melting techniques to secure components
  • Ensure proper fitment around airbag switch and other controls

Troubleshooting

Common issues after conversion:

  • Cluster lights not working: Check connections between pins 10 and 13
  • Dome light issues: Verify proper wiring to the dimmer function
  • Headlights staying on: Ensure switch is properly seated and wired

Note: Some trial and error may be necessary to achieve full functionality.

Benefits of Upgrade

  • Improved aesthetics with turn-style switch
  • Better durability compared to older pull-style switch
  • Potential for additional features (e.g., fog light integration)

This upgrade requires some electrical knowledge but can significantly enhance your 1998 Dodge Ram's lighting controls and dashboard appearance.
