Connect Your Bosch LSU 4.9 Wideband Sensor to Your Haltech Nexus or Elite PRO Plug-In ECU Without Custom Wiring
The Haltech HALHT-131002 is the Bosch LSU 4.9 Wideband O2 Sensor Harness for Haltech Nexus Series ECUs and Elite PRO Plug-In ECUs designed for Ford Falcon Barra-engined vehicles. The HALHT-131002 is a 1.2-meter pre-terminated harness that mates the Bosch LSU 4.9 wideband sensor connector to the wideband input on compatible Haltech ECUs, eliminating the need for custom wiring or pin-out sourcing when adding wideband air-fuel ratio monitoring to a Haltech-managed engine.
Key Features
- Designed for Bosch LSU 4.9 Sensors: The HALHT-131002 uses the correct connector and wire gauge for the Bosch LSU 4.9 sensor family, the industry-standard wideband O2 sensor used in Haltech's wideband controllers and compatible ECU inputs
- Pre-Terminated Both Ends: Both the sensor-side connector and the ECU-side pins are pre-terminated from the factory, allowing direct installation without cutting, soldering, or custom termination
- 1.2 Meter Length (4 Feet): The HALHT-131002 is 1.2 meters (approximately 4 feet) long, providing enough reach for most firewall-mounted ECU installations without creating excessive slack
- High-Temperature Wire and Sheathing: The harness uses high-temperature rated wire insulation and protective sheathing designed to withstand underhood heat exposure near exhaust and engine components
- Plug-and-Play for Supported ECUs: Compatible with Haltech Nexus Series and Elite PRO Plug-In ECUs for Ford Falcon Barra engines without requiring additional adapters

Frequently Asked Questions
What is the HALHT-131002?The HALHT-131002 is the Haltech Bosch LSU 4.9 Wideband O2 Sensor Harness for Haltech Nexus Series and Elite PRO Plug-In ECUs (Ford Falcon Barra). It is a 1.2-meter pre-terminated harness that connects a Bosch LSU 4.9 wideband sensor directly to a compatible Haltech ECU without custom wiring.
What ECUs is the HALHT-131002 compatible with?The HALHT-131002 is designed for use with Haltech Nexus Series ECUs and the Haltech Elite PRO Plug-In ECU for Ford Falcon Barra-engined vehicles. Verify compatibility with your specific ECU model number on Haltech's product page before ordering.
Does the HALHT-131002 include a Bosch LSU 4.9 sensor?No. The HALHT-131002 is a harness only and does not include a wideband O2 sensor. A Bosch LSU 4.9 sensor must be purchased and installed in your exhaust separately before connecting to this harness.
Will the HALHT-131002 work with a Haltech wideband controller instead of a direct ECU input?The HALHT-131002 is designed for direct ECU wideband inputs on the specified Haltech models. Compatibility with a standalone Haltech wideband controller depends on the controller's sensor connector type. Check Haltech's documentation for the specific wideband controller you are using.
How long is the HALHT-131002 harness?The HALHT-131002 is 1.2 meters (approximately 4 feet) in length. This is typically sufficient for most mounting locations but may require extension for remote firewall ECU placements with long runs to exhaust-mounted sensors.
Is the HALHT-131002 compatible with other wideband controllers or brands?The HALHT-131002 is optimized for Haltech ECU inputs. The Bosch LSU 4.9 connector on the sensor end is a standard connector type and may be compatible with other wideband controllers that accept LSU 4.9 sensors, but the ECU-side connector is Haltech-specific. Verify before use in non-Haltech applications.
What temperature rating does the HALHT-131002 wire have?The HALHT-131002 uses high-temperature rated wire and sheathing designed for underhood environments near exhaust and engine heat sources. Specific temperature ratings are listed in Haltech's product documentation.
What is the warranty on the HALHT-131002?Haltech covers their wiring harnesses under their standard warranty for defects in materials and workmanship. Contact Haltech support directly with the part number HT-131002 to confirm current warranty terms.
Installation Instructions
- Ensure your Bosch LSU 4.9 wideband O2 sensor is installed in the exhaust at the correct bung location, typically 1 to 2 bung diameters upstream of any collector or merge point.
- Route the HALHT-131002 harness from the sensor location through the firewall or along the engine bay to the ECU wideband input location.
- Connect the sensor-side connector to the Bosch LSU 4.9 sensor's pig-tail connector.
- Connect the ECU-side pins to the corresponding wideband input pins on the Haltech ECU wiring connector. Refer to the Haltech pinout chart for your specific ECU model.
- Secure the harness with cable ties away from heat sources, sharp edges, and rotating components.
- Configure the ECU software to enable and calibrate the wideband O2 input channel for the Bosch LSU 4.9 sensor type.
