5. Konfigurazioa eta instalazioa
Follow these steps for proper installation of the tail light converter:
- Prestaketa: Gather necessary tools (wire strippers, crimpers, electrical tape, circuit tester, mounting hardware). Disconnect the vehicle's negative battery terminal.
- Identify Vehicle Wires: Using a circuit tester, identify the following wires on your vehicle's taillight harness:
- Tail Light (running lights)
- Stop Light (brake lights)
- Ezkerrera Biratzeko Seinalea
- Eskuineko biratzeko seinalea
- Lurra
- Connect Converter Input Wires: Splice the converter's input wires to the corresponding vehicle wires. Ensure secure connections using appropriate connectors or soldering, and insulate thoroughly with electrical tape or heat shrink tubing.

- Bihurgailua Berdea Wire → Vehicle Eskuineko biratzeko seinalea Hari
- Bihurgailua Zuria Wire → Vehicle Lurra (ensure a good chassis ground connection)
- Mount Converter: Secure the converter unit in a dry, protected area of the vehicle, such as inside the trunk or under the rear bumper, using screws or zip ties. Ensure it is not exposed to direct water spray or excessive heat.
- Connect to Trailer: Route the converter's 4-flat output connector to the rear of the vehicle where it can easily connect to the trailer's 4-flat plug. Use the included cover to protect the connector when not in use.
- Proba sistema: Reconnect the vehicle's battery. Connect a trailer or a trailer light tester to the 4-flat connector. Test all lighting functions: tail lights, brake lights, left turn signal, and right turn signal. Ensure all lights operate correctly and independently.
6. Funtzionamendu-argibideak
Once properly installed, the Tekonsha 119178 Tail Light Converter operates automatically. When the vehicle's lights are activated, the converter processes the signals and sends the correct output to the trailer's lighting system. No manual intervention is required during operation.
- Before each towing trip, ensure the 4-flat connector is securely plugged into the trailer and that all trailer lights are functioning correctly.
- The converter is designed to work with both LED and incandescent bulbs on both the vehicle and trailer, providing flexibility for various setups.
7. Mantentzea
Minimal maintenance is required for the Tekonsha 119178 Tail Light Converter:
- Ohiko ikuskapena: Periodically inspect all wiring and connections for signs of wear, corrosion, or damage. Repair or replace any compromised components immediately.
- Konexio garbiak: Keep the 4-flat connector pins clean and free of dirt or debris. Use dielectric grease on the pins to prevent corrosion, especially in harsh environments.
- Muntaketa segurua: Ensure the converter unit remains securely mounted in its designated location.
8. Arazoak
If you encounter issues with your tail light converter, refer to the following troubleshooting guide:
| Arazoa | Kausa posiblea | Irtenbidea |
|---|---|---|
| No trailer lights functioning. | Loose or corroded connections; blown vehicle fuse; faulty trailer wiring. | Check all connections, vehicle fuses, and trailer wiring. Ensure a good ground connection. |
| Trailer lights not functioning correctly (e.g., brake lights activate with turn signal). | Incorrect wiring connections to the vehicle. | Re-verify all input wire connections to the vehicle's tail, stop, and turn signal wires. |
| Converter stops working intermittently or after a short circuit. | Integrated short circuit protection activated. | Disconnect the trailer. Inspect trailer wiring for shorts. The converter's protection is re-settable and should resume normal operation once the fault is cleared. |
| One specific trailer light not working. | Faulty trailer bulb; issue with trailer's internal wiring; specific output wire from converter is loose. | Check the trailer bulb. Inspect the trailer's wiring. Verify the corresponding output wire from the converter to the 4-flat connector. |
