Difficulty: Beginner · About 15 min · Dodge Ram

Replace the under-hood lamp wiring harness on 1998–2010 Dodge Ram models by releasing its connectors and retaining clips along the hood.

Steps

1. Disconnect the harness

   Switch off the lamp and ignition, then locate the harness connector at the lower end of the circuit. Slide its secondary lock back and press the release tab to unplug it.

2. Remove the old wiring

   Release the harness cover clips with suitable pliers and avoid crushing the wire insulation. Unplug the harness from the hood lamp and note the route and clip positions.

3. Install the replacement harness

   Connect the new harness to the lamp, then press its retaining clips into the original hood openings. Route the wiring away from hinges and sharp edges before reconnecting the lower connector.

4. Test the lamp

   Engage the connector’s safety lock and confirm the wiring is retained securely. Open and close the hood carefully while checking that the lamp operates and the harness does not snag.

Check your vehicle’s repair manual for exact specifications and fit.
