4. Configuration et installation
The LPHFD31 T-Harness simplifies the process of integrating aftermarket audio components into your vehicle's existing non-amplified factory stereo system. It provides clearly labeled pigtail harnesses for front and rear speaker leads, allowing for easy connection to a Line Output Converter (LOC) or directly to an aftermarket amplifier with high-level inputs.
4.1 Étapes générales d'installation
- Déconnecter la batterie : Avant d'entreprendre tout travail électrique, débranchez la borne négative de la batterie du véhicule afin d'éviter les courts-circuits ou les dommages électriques.
- Access Factory Radio: Carefully remove the vehicle's factory radio to gain access to the wiring harness. Refer to your vehicle's service manual for specific instructions on radio removal.
- Faisceau en T de connexion : Disconnect the factory wiring harness from the back of the radio. Connect the PAC LPHFD31 T-Harness in-line with the factory radio and the vehicle's wiring. The T-Harness will have connectors that match the factory plugs.
- Identify Speaker Leads: The LPHFD31 T-Harness features clearly labeled pigtail harnesses for front and rear speaker leads. These wires will provide the high-level audio signal from your factory radio.
- Connect to Aftermarket Equipment:
- For Line Output Converter (LOC): If using an LOC (e.g., AudioControl LC2i), connect the appropriate speaker leads from the T-Harness to the high-level inputs of the LOC. The LOC will convert these signals to low-level RCA outputs for your aftermarket amplifier.
- For Aftermarket Amplifier with High-Level Inputs: If your aftermarket amplifier accepts high-level inputs, connect the speaker leads directly from the T-Harness to the ampBornes d'entrée de haut niveau de l'amplificateur.
- Connexions d'alimentation et de terre : Ensure your aftermarket amplifier and/or LOC receive proper power (+12V), ground, and remote turn-on connections. The T-Harness may provide a remote turn-on output (GTO signal sensing input on some LOCs) or you may need to tap into an accessory wire.
- Câblage de l'itinéraire : Carefully route all new wiring to avoid interference, pinching, or damage. Secure wiring with zip ties or electrical tape.
- Remonter: Once all connections are secure and verified, reassemble the vehicle's dashboard and reconnect the battery.

5. Principes de fonctionnement
The PAC LPHFD31 T-Harness is a passive component that facilitates the integration of aftermarket audio equipment. It does not actively process audio signals or control vehicle functions. Its primary role is to provide a clean, accessible point to tap into the factory speaker wiring without cutting or modifying the original harness.
- Signal Transfer: The harness transfers the high-level audio signals from your factory radio to the connected aftermarket devices (e.g., LOC, amplificateur).
- Factory Radio Retention: Your factory radio will continue to operate as normal, controlling volume, source selection, and other features. The T-Harness simply provides an output for additional audio components.
- Aftermarket Component Control: The operation and sound quality of your aftermarket audio system will be controlled by the connected LOC, amplifier, and other components. Adjustments to bass, gain, and crossover frequencies will be made on these devices.
6. Entretien
The PAC LPHFD31 T-Harness requires minimal maintenance. Once installed correctly, it is designed for long-term, reliable operation.
- Inspection régulière : Vérifiez régulièrement toutes les connexions pour vous assurer qu'elles restent bien fixées et exemptes de corrosion.
- Propreté: Keep the area around the harness and connected components clean and free of dust or debris.
- Éviter l’humidité : Ensure the harness and connections are protected from moisture and extreme temperatures.
- Vérification professionnelle : If you experience any audio issues after installation, consult a professional car audio technician.
