Preparation

1. Park vehicle on level surface and engage parking brake.
2. Disconnect battery negative terminal and wait 2 minutes for any residual electrical charge to dissipate.
3. Determine camera mounting location (license plate frame mount or rear fascia surface mount).
4. Determine display mounting location (replacement rearview mirror with integrated display or dash-mounted screen).
5. Plan wire routing path from rear of vehicle to cabin, typically through trunk weatherstrip grommet or existing body penetrations.
6. Review camera kit instructions for specific wiring requirements and verify camera triggers from reverse light power or dedicated switch.

Procedure

1. 1

   Mount backup camera at rear of vehicle
   Install the backup camera in the chosen location. For license plate mount: remove the 2 license plate fasteners, position the camera bracket behind the plate, and reinstall the plate through the bracket. For surface mount: clean the mounting area thoroughly, test-fit the camera to ensure proper viewing angle (typically 15-20 degrees downward), and secure with adhesive backing or the provided fasteners. Ensure the camera lens has unobstructed view of the area directly behind the vehicle and does not interfere with license plate visibility or lighting.
2. 2

   Access reverse light wiring for trigger signal
   Open the rear hatch/trunk. Locate the reverse light within the rear lamp assembly in the rear fascia. Remove or fold back the rear cargo area trim/liner as necessary to access the back of the reverse light housing. You will find connectors or wiring leading to the reverse lights. Identify the reverse light positive wire (typically shows 12V only when the manual transmission is shifted into reverse, activating the reverse lamp switch) using a multimeter or test light. This wire will provide the trigger signal to activate the camera when backing up.
3. 3

   Connect camera power and trigger wires
   Connect the camera's power wire to the reverse light positive wire using a butt connector, solder splice, or T-tap connector. This provides both power to the camera and the trigger signal to activate the display when reverse gear is engaged. Connect the camera ground wire to a nearby body ground point (bare metal, cleaned of paint) or to the reverse light ground wire. Secure all connections with heat shrink tubing or electrical tape. Test the connection by turning the ignition to accessory mode and shifting to reverse (with parking brake engaged) to verify camera receives power.
4. 4

   Route video cable from camera to cabin
   Route the camera's video cable from the rear mounting location toward the cabin. Follow existing wiring harnesses along the driver side of the vehicle. Locate the trunk weatherstrip grommet or existing body pass-through on the driver side where the trunk meets the cabin. Carefully create a small opening in an existing grommet or use a factory pass-through if available. Use fish tape or a stiff wire to pull the video cable through the opening into the cabin area. Protect the cable with wire loom or split tubing where it passes through metal body openings. Secure the cable along its route with cable ties to existing harness anchor points or body clips, ensuring it does not contact hot exhaust components, sharp edges, or moving parts.
5. 5

   Remove interior trim to route video cable to display location
   Remove the necessary interior trim panels to route the video cable from the trunk pass-through to the display location. For dash-mounted displays: remove the driver side door sill trim, lower A-pillar trim, and carefully pry away the lower dash side panels to access the routing path. For rearview mirror displays: route the cable up the A-pillar area toward the headliner. Use plastic trim tools to carefully release trim panel clips without breaking them. Route the video cable through the newly accessed areas, securing with cable ties at regular intervals to prevent rattling. Keep cable away from pedals, steering column moving parts, and airbag deployment zones.
6. 6

   Install display screen
   Install the backup camera display in the chosen location. For replacement rearview mirror displays: remove the existing rearview mirror by loosening the set screw or releasing the mounting clip (varies by mirror type), disconnect any auto-dimming or compass wiring if equipped, install the new mirror with integrated display per kit instructions, and connect to the windshield mount. For dash-mounted displays: position the display on the dash in a location that does not obstruct gauges or driver visibility, secure with the provided mount (adhesive or suction cup), and ensure all mounting surfaces are clean and dry. Run power wire from the display toward the fuse panel area.
7. 7

   Connect video cable to display
   Connect the video cable routed from the camera to the video input on the display unit. Most aftermarket systems use RCA-style connectors or dedicated multi-pin connectors. Ensure the connection is fully seated and secure. Coil any excess video cable length neatly and secure it behind the trim panels with cable ties, keeping it away from moving parts and heat sources.
8. 8

   Connect display power
   Connect the display power wire to a switched 12V source that is active with ignition on. Recommended connection points include an accessory circuit in the fuse panel or tapping into the ignition-switched wire feeding the radio or instrument cluster (verify with multimeter that the source is 12V with ignition on and 0V with ignition off). Connect the display ground wire to a nearby chassis ground point. For displays with separate reverse trigger wire, connect this to the same reverse light positive wire used for the camera trigger. Use appropriate connectors and heat shrink tubing for all connections. Do not connect display power directly to battery positive as this will drain the battery when vehicle is off.
9. 9

   Secure all wiring and verify routing
   Inspect the entire wire routing path from camera to display. Secure all loose wiring with cable ties at 12-18 inch intervals. Ensure wires do not hang loose, contact moving parts (pedals, steering column, shift linkage), rest on hot components (exhaust, engine), or route through areas where they could be pinched by trim panels during reinstallation. Use additional wire loom or split tubing in any areas where wires pass through body openings or could contact sharp edges. Verify that wiring in the trunk area is secured away from items that may be loaded in the trunk.
10. 10

    Test camera system operation
    Reconnect the battery negative terminal. Turn the ignition to the on position. Depress the clutch and shift the manual transmission into reverse with the parking brake engaged (ignition on). Verify that the display activates and shows the camera image clearly. Check that the image is properly oriented (not upside down or mirror-reversed unless intentional). Verify that any distance grid lines or overlays are properly aligned and useful. Test in various lighting conditions if possible. If the display does not activate, verify all power connections, trigger wire connections, and video cable connections are secure and correct.
11. 11

    Adjust camera angle and settings
    With the camera system operational, adjust the camera mounting angle if the bracket allows adjustment to optimize the rearward view. The camera should show the ground approximately 2-3 feet behind the rear bumper at the bottom of the screen and extend the view to 10-15 feet or more at the top of the screen. Access the display menu settings (per kit instructions) to adjust brightness, contrast, color, and grid line display as preferred. Some systems allow mirror/flip settings if the image orientation needs correction.
12. 12

    Reinstall all interior trim panels
    Reinstall all removed interior trim panels in reverse order of removal. Align each panel carefully with its mounting clips and press firmly to seat the clips. Verify that all panels are flush and secure with no gaps or rattles. Reinstall door sill trim by aligning and pressing down until clips engage. Ensure no wiring is pinched behind trim panels during installation. Verify that all trim fasteners are properly secured.

Reassembly

1. Verify all interior trim panels are properly seated and secure.
2. Verify no tools or parts remain in the trunk or cabin work areas.
3. Confirm battery negative terminal is reconnected and tight.

Verification

• Start the vehicle and shift into reverse. Verify the backup camera display activates automatically.
• Confirm the camera image is clear, properly oriented, and provides adequate view of the area behind the vehicle.
• Verify the display deactivates or switches to another mode when shifted out of reverse.
• Check that all interior trim panels are secure and no rattles are present.
• Verify no warning lights are illuminated on the instrument cluster related to electrical issues.
• Test drive the vehicle and verify backup camera continues to function correctly during actual use.
