This procedure covers the removal and replacement of the instrument cluster on a 2007 Ram 3500 with 5.9L Cummins diesel engine.

Warnings

Tools required

Parts

• Instrument cluster assembly × 1 — Use OEM specification
• Dash trim panel clips (if broken) × 1 — Mopar 6503598AA or equivalent

Preparation

1. Park vehicle on level surface and set parking brake
2. Turn ignition to OFF position and remove key
3. Disconnect negative battery cable and wait 2 minutes for airbag system to discharge
4. Adjust steering wheel to lowest and most extended position for access
5. Ensure interior work area is well lit

Procedure

1. 1

   Remove steering column covers
   Remove the two Phillips screws from the bottom of the lower steering column cover. Separate the lower cover by pulling it away from the column. Remove the upper steering column cover by lifting upward and pulling toward the rear of the vehicle to disengage the retaining clips.
2. 2

   Remove knee bolster panel
   Locate and remove the Phillips screws securing the lower knee bolster panel beneath the steering column. There are typically 3-4 screws along the bottom edge. Carefully pull the panel down and toward you to release any remaining clips. Disconnect any electrical connectors if equipped with courtesy lighting.
3. 3

   Remove instrument cluster bezel
   Using a trim panel tool, carefully pry around the perimeter of the instrument cluster bezel starting at the bottom corners. Work your way around releasing all retaining clips. The bezel surrounds the cluster and extends toward the center stack. Pull the bezel straight back once all clips are released. The bezel surrounds the cluster and extends toward the center stack.
   ⚠Apply gentle, even pressure when releasing clips to avoid cracking the bezel or breaking mounting tabs.
4. 4

   Remove cluster mounting screws
   Locate the four screws securing the instrument cluster to the dash frame. There are typically two screws along the top edge and two along the bottom edge. Remove all four screws using a Phillips screwdriver or 7mm socket depending on your specific hardware. Keep screws organized for reinstallation.
5. 5

   Pull cluster forward
   Carefully pull the instrument cluster straight toward you approximately 3-4 inches. Support the cluster with both hands as you pull it forward. There should be enough wiring harness slack to access the rear connections. Do not force the cluster if it does not move easily—check for any missed fasteners.
6. 6

   Disconnect electrical connectors
   Reach behind the instrument cluster and locate the main wiring harness connectors. There are typically 2-3 large connectors on the back of the cluster. Press the release tabs on each connector and pull straight back to disconnect. Note the orientation and position of each connector for reassembly. Note the orientation and position of each connector for reassembly.
   ℹ️Take a photo of connector positions before removal to aid in correct reassembly.
7. 7

   Remove instrument cluster
   With all connectors disconnected, carefully pull the instrument cluster completely out of the dash opening. Handle the cluster by the edges and avoid touching the gauge faces or display screen. Inspect the cluster mounting area for any debris or damaged wiring.
8. 8

   Install replacement cluster
   Position the new or repaired instrument cluster near the dash opening. Reconnect all electrical connectors to the back of the cluster, ensuring each connector clicks fully into place and the locking tabs engage. Verify all connections are secure before proceeding. Verify all connections are secure before proceeding.
9. 9

   Seat cluster and install screws
   Carefully push the instrument cluster into the dash opening, ensuring no wiring is pinched behind it. Align the screw holes with the mounting points in the dash frame. Install all four cluster mounting screws and tighten evenly in a cross pattern. Screws should be snug but not overtightened to avoid cracking the cluster housing.
10. 10

    Reinstall cluster bezel
    Position the instrument cluster bezel over the cluster and align all mounting points. Press firmly around the perimeter of the bezel until all retaining clips snap into place. Verify the bezel is seated flush against the dash with no gaps.
11. 11

    Reinstall knee bolster and column covers
    Reconnect any electrical connectors to the knee bolster panel if equipped. Position the panel and press upward until clips engage, then install the retaining screws. Position the upper steering column cover over the column and press down to engage clips. Install the lower cover and secure with the two Phillips screws.

Reassembly

1. Reconnect negative battery cable
2. Verify all trim panels are properly seated with no gaps or loose clips
3. Check that steering column moves freely without interference from covers

Verification

• Turn ignition to RUN position without starting engine and verify all gauges perform their self-test sweep
• Verify all indicator lights illuminate during bulb check
• Check that odometer displays correct mileage
• Start engine and verify all gauges respond correctly (oil pressure, coolant temperature, fuel level, tachometer)
• Test all warning lights function properly (check engine, glow plug, battery, etc.)
• Verify instrument panel dimmer control functions properly
• Check that trip computer and message center display correctly if equipped
• Verify transmission gear indicator displays correctly on automatic transmission vehicles
• Test that speedometer reads accurately during test drive
