Installation reference images
Before you begin
- Vehicle/product: 2022-2026 Toyota GR86 / Subaru BRZ Sequential LED Tail Lights.
- SKU check: Confirm your kit SKU or variant matches T-GR86-SR, T-GR86-SDG before removing original parts.
- Reference-first workflow: Review the installation reference images on this page before removing trim or connecting wiring. This guide includes confirmed details from the available reference text and images.
- Power and safety: Switch the vehicle off before unplugging connectors. Disconnect the negative battery terminal when handling wiring, fuse taps, or exposed circuits.
- Protect the vehicle: Use clean towels or masking tape around painted panels and trim edges. Do not force clips or pry against painted surfaces.
- No connector grease: Do not apply dielectric grease or weather-sealing grease to connectors or sockets.
- Rear lamp note: Leave trunk, hatch, cargo, or tailgate trim open until every lighting function passes testing.
Reference image checkpoints
- Connector layout: Compare each vehicle connector, adapter harness, and included extension wire with the reference images before powering the RIGNOX tail lights.
- Inner and outer lamp sequence: If the vehicle has trunk-lid, hatch, through-light, or outer corner lamps, remove and reinstall them in the sequence shown in the reference images.
- Harness routing: Route linking harnesses through the indicated grommets or trim paths. Keep wiring away from hinges, latch movement, weather seals, exhaust heat, and sharp sheet-metal edges.
- Transferred parts: Move cameras, brackets, BLIS modules, bulb holders, seals, or decorative plates only when the matching reference image shows that transfer.
- RGB/app variants: Confirm controller power, pairing, mode change, and local road-lighting use before final trim reassembly.
Confirmed reference details
- Function points: The reference identifies turn signal, side lamp, auxiliary running lights, running/brake lights, turn-signal projection, and main plug.
- Dynamic plug: Inserted mode enables turn-signal running plus running-light dynamics. Unplugged mode disables flowing turn signal and dynamic running light.
- Reference match: The function diagram is shared with the supplied tail-lamp reference. Confirm connector shape and supplied harness before powering the GR86/BRZ kit.
- RGB variant: RGB versions use the QR/app workflow shown in the reference image.
Tools and supplies
- Trim removal tool or panel clip tool
- Metric socket and ratchet set; confirm the exact socket sizes against the reference images before removal
- Phillips and flat screwdrivers
- Clean microfiber towels and masking tape for painted trunk, hatch, tailgate, and quarter-panel edges
- Electrical tape and zip ties for securing included harnesses only
- A helper for brake-light and turn-signal testing
Remove the original tail lights
-
Remove the side trim cover: Open the trunk and pull off the small black plastic cover beside the tail light to expose the mounting fasteners.
-
Remove the tail light fasteners: Use a 10 mm socket to remove the three fasteners securing the factory tail light.
-
Remove the factory tail light: Pull the tail light outward from the vehicle, press the connector locking tab, and disconnect the factory wiring harness.
Install the RIGNOX tail lights
-
Connect the new tail light harness: Connect the new LED tail light harness to the factory wiring connector and make sure the plug is fully seated.
-
Reinstall and secure the tail light: Align the tail light with the body opening, push it into its original mounting position, tighten the three fasteners, and reinstall the side trim cover.
-
Test all lighting functions: Turn on the vehicle power and test the startup animation, parking lights, brake lights, and sequential turn signals to confirm that both LED tail lights operate correctly.
Electrical and function test
- Test parking/running lights, brake lights, left and right turn signals, hazards, reverse lights, fog light if supported, and startup animation if equipped.
- For through-light or linking-harness products, test both sides before reinstalling hatch, trunk, or cargo trim.
- If a camera, BLIS module, bulb holder, resistor, decoder, or controller was transferred, confirm that related vehicle functions have no warning message.
- For RGB/app variants, confirm controller power, app pairing, normal mode, RGB mode, speed/brightness controls, and the mode required for road use.
- After all tests pass, reinstall trim panels and close the trunk, hatch, or tailgate slowly to confirm no wire is stretched or pinched.
Final check
- All connectors are fully seated and locked.
- All included harnesses are secured away from movement, sharp edges, water paths, and heat sources.
- Both lamps sit flush with even body gaps, properly seated seals, and no trapped harness under the weather seal.
- All tail lights functions test correctly on both sides with a helper operating the controls.
- No warning lights, hyperflash, flickering, abnormal heat, moisture entry, or loose modules remain after a short function check.
Troubleshooting
- One tail light does not turn on: Recheck the main connector, side-specific extension wire, and any plug-in adapter shown in the reference images.
- Brake, reverse, running, or turn function is wrong: Stop and compare the connector choice and wire routing with the reference images before moving pins or changing wiring.
- Warning, flicker, or hyperflash appears: Confirm any included decoder, resistor, or harness adapter is installed exactly for this product and vehicle trim.
- Trim will not sit flush: Check for a trapped harness, misaligned clip, folded weather seal, or incorrect grommet position.
- RGB/app feature does not respond: Confirm the product variant supports RGB, the controller has power, and the app or remote is paired before closing trim.
