Before You Begin
This guide walks you through installing an OEM integrated backup camera on your Scion FR-S or Subaru BRZ. The system uses a plug-and-play harness that connects to your factory head unit — no wire cutting, no splicing, and no aftermarket monitor required.
Read through every step before starting. Keep the instruction sheet included in your kit handy, as it contains the exact connector diagrams and any model-year-specific notes that supersede this general guide.
Step 1 — Gather Tools and Unbox the Kit
You'll need a plastic trim removal tool, a Phillips-head screwdriver, and a clean workspace. Unbox your kit and confirm all components are present: the camera, plug-and-play harness, and any mounting hardware.
Step 2 — Disconnect the Battery
Before working on the electrical system, disconnect the negative terminal of the vehicle battery. This prevents accidental shorts. Wait a few minutes before proceeding to allow any residual capacitance to discharge.
Step 3 — Remove the Head Unit Surround
Using the plastic trim removal tool, carefully pry around the edges of the head unit surround panel. Work slowly and evenly to avoid damaging the trim clips. Once the panel is loose, disconnect any wire harnesses attached to it and set it aside.
Step 4 — Unbolt the Factory Head Unit
Remove the Phillips screws securing the head unit to the dash frame. Gently slide the head unit forward — the factory connectors will still be attached behind it. Do not force anything; if it feels stuck, re-check for screws you may have missed.
Step 5 — Connect the Plug-and-Play Harness
Disconnect the factory harness from the back of the head unit. Connect the provided plug-and-play harness between the vehicle's factory wiring and the head unit. The connectors are keyed and only fit one way. Refer to your kit's instruction sheet for the exact pinout diagram.
Step 6 — Route the Camera Cable
Run the camera's video cable from the head unit area, along the headliner or under the door sill trim, to the rear of the vehicle. Route it through existing grommets into the trunk lid area. Avoid pinching the cable or running it near moving parts or sharp edges.
Step 7 — Mount the Camera and Test
Mount the camera in the designated OEM location (typically above the license plate). Reconnect the battery. Start the vehicle and shift into reverse — the factory head unit display should automatically switch to the camera view.
If everything works correctly, reinstall the trim panels in reverse order of removal.
Troubleshooting
No image when shifting to reverse
Verify the camera connector is fully seated at both ends. Check that the reverse signal wire from the harness is properly connected. Some vehicles require OBD-II activation — see our Programmers category for compatible tools.
Image is upside down or mirrored
Many cameras have a polarity or orientation switch on the back housing. Flip it to correct the image orientation.
Image is black and white or flickering
Check for loose connections and verify the camera's power wire is connected to a stable reverse light circuit. A loose ground connection can cause flickering.
Frequently Asked Questions
Will this procedure work with my exact model year?
This guide applies to 2012 through 2016 Scion FR-S and Subaru BRZ vehicles with the factory head unit. Check your specific product page for exact compatibility.
Do I need to cut any wires?
No. The installation uses a plug-and-play harness that connects between existing factory connectors.
Will this void my factory warranty?
Under the Magnuson-Moss Warranty Act, installing an aftermarket accessory generally does not void your factory warranty. See our FAQ page for more on warranty impact.
