Replace or install a backup camera on a 2015 Kia Forte, including removal of the trunk trim panel, camera installation, and wiring connection to the head unit.

Warnings

Tools required

Parts

• Backup camera assembly × 1 — Use OEM specification or compatible aftermarket
• Trunk trim panel clips (if damaged) × 1 — Use OEM specification
• Camera mounting grommet (if not included) × 1 — Use OEM specification
• Wire routing clips × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake.
2. Open trunk and remove all items from cargo area for clear access.
3. Disconnect negative battery terminal and wait 3 minutes for system discharge.
4. Photograph existing wire routing if replacing an existing camera.

Procedure

1. 1

   Remove trunk interior trim panel
   Open the trunk and locate the interior trim panel covering the trunk lid area. Use a trim removal tool to carefully pry out the plastic clips securing the trim panel. Start at the edges and work around the perimeter. Remove any Phillips screws if present (typically 2-3 screws). Gently pull the trim panel away from the trunk lid to access the camera mounting location.
2. 2

   Locate camera mounting position
   With the trim panel removed, locate the factory camera mounting location on the trunk lid exterior, typically centered above the license plate area. If replacing an existing camera, note the mounting hole and grommet. For new installations, verify the mounting hole is properly positioned and deburred. Inspect the rubber grommet for damage and replace if necessary.
3. 3

   Route camera wiring harness
   Feed the camera wiring harness through the trunk lid from exterior to interior, passing through the rubber grommet. Route the wire along the existing wire loom on the driver's side of the trunk lid. Use wire routing clips to secure the harness and prevent interference with trunk operation. Ensure adequate slack for trunk opening and closing movement.
4. 4

   Install backup camera assembly
   Insert the backup camera into the mounting hole from the exterior of the trunk lid. Ensure the rubber grommet is properly seated to prevent water intrusion. If the camera uses mounting fasteners, hand-tighten first to verify proper alignment, then torque to specification. Verify the camera lens is clean and oriented correctly (top marked if applicable).
   Torque spec

   Mounting Bolts26 Nm (19 lb-ft)
5. 5

   Route wiring through trunk to cabin
   Route the camera harness from the trunk lid down the left trunk hinge area into the main trunk cavity. Follow existing wire harnesses through the trunk pass-through into the cabin area. Use the factory wire passage points, typically on the driver's side behind the rear seat or through the trunk side panel. Secure wiring with clips to prevent rattles.
6. 6

   Connect to reverse light power source
   Locate the reverse light circuit in the trunk area (typically at the left tail light assembly). The camera requires power from the reverse light circuit to activate when the transmission is in reverse. Use a test light to verify the reverse light power wire (typically green/white). Make the connection using a proper tap connector or solder and heat shrink, then secure with electrical tape.
7. 7

   Route video cable to head unit
   Route the video cable from the trunk area along the driver's side under the door sills. Remove the scuff plates as needed to access the wiring channel. Feed the cable forward to the dashboard area, following existing harnesses. Keep the video cable away from high-voltage or high-current wires to minimize interference.
8. 8

   Connect to head unit
   Access the back of the head unit by removing the center console trim panels. Locate the camera input connector on the head unit (typically labeled 'CAM IN' or similar). Connect the video cable to the appropriate input. If installing an aftermarket camera, verify compatibility and use any required adapters. Ensure all connections are fully seated and secure.
9. 9

   Connect ground wire
   Connect the camera system ground wire to a clean, unpainted metal ground point in the trunk area. Remove any paint or corrosion from the ground contact point using sandpaper or a wire brush. Install the ground wire terminal and secure with the ground bolt torqued to specification. Ensure solid metal-to-metal contact for reliable operation.
   Torque spec

   Ground Bolt13 Nm (10 lb-ft)
10. 10

    Reinstall interior trim panels
    Reinstall the trunk interior trim panel by aligning the clips with their mounting holes. Press firmly around the perimeter until all clips snap into place. Install any screws removed during disassembly and torque to specification. Reinstall center console trim panels and door sill plates. Verify all panels are secure and fit properly.
    Torque spec

    Cover Screws10 Nm (8 lb-ft)
11. 11

    Reconnect battery and initialize system
    Reconnect the negative battery terminal and torque the terminal bolt to specification. Turn the ignition to the ON position without starting the engine. The head unit should boot up and initialize. Some vehicles may require a steering angle sensor calibration or system reset through the settings menu after battery reconnection.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

1. Ensure all trim panels are securely fastened with no gaps or loose clips.
2. Verify all wire routing is secure and wires are not pinched by trim panels or trunk lid operation.
3. Check that the camera lens is clean and free from fingerprints or debris.

Verification

• Start the engine and shift the transmission into reverse. The backup camera image should appear on the head unit display within 1-2 seconds.
• Verify the camera image is clear, properly oriented, and free from interference or static.
• Check that guide lines (if equipped) appear correctly on the display and align with reference objects behind the vehicle.
• Operate the trunk lid through full open and close cycles several times to ensure wiring has adequate slack and does not bind.
• Verify no warning lights are illuminated on the instrument cluster.
• Test in various lighting conditions (daylight and night) to confirm proper camera operation.
