MaxxECU SPORT 3-Meter Flying-Lead Wiring Harness

MaxxECU SPORT 3-Meter Flying-Lead Wiring Harness

Part Number: 1915

The MaxxECU SPORT flying-lead harness provides the main wiring interface between a MaxxECU SPORT ECU and the engine, sensors, ignition system, injectors, electronic throttle, power distribution, and supporting vehicle systems.

The harness is manufactured with thin-wall automotive wire and printed circuit identification to simplify routing, termination, and troubleshooting during a custom installation. The ECU connector is pre-terminated, while the application side is left unterminated so the harness can be built around the specific engine and vehicle configuration.

Key Features

• Designed specifically for the MaxxECU SPORT ECU
• Approximately 3-meter conductor length
• Pre-terminated MaxxECU SPORT ECU connector
• Flying-lead construction for custom engine and vehicle installations
• Thin-wall automotive-grade wire
• Printed circuit identification along the individual conductors
• Provides wiring for the SPORT ECU’s:
  • Injector and ignition channels
  • Crankshaft and camshaft inputs
  • Analog and temperature inputs
  • Digital inputs
  • General-purpose outputs
  • Electronic-throttle motor outputs
  • CAN bus
  • Integrated wideband-lambda connection
  • ECU power and grounds

Application Notes

• This harness is intended for universal custom wiring. Engine-side sensor, injector, ignition-coil, throttle, relay, power-distribution, and auxiliary connectors are not supplied unless specifically shown as included.
• The harness is designed for the MaxxECU SPORT connector and pinout. It is not a universal replacement harness for other MaxxECU models.
• Confirm the ECU hardware revision and use the corresponding current MaxxECU SPORT wiring diagram before terminating the harness.
• Harness construction varies by revision:
  • REV1 uses mostly 3-meter conductors and includes a pre-terminated GT150 auxiliary connector.
  • REV2 uses 3-meter conductors throughout and does not include a pre-attached GT150 auxiliary connector.
• Shielded crank, cam, and wideband wiring should be terminated and grounded according to MaxxECU’s published wiring instructions.
• The sensor-ground circuit must remain isolated from chassis ground and connected only as specified in the MaxxECU wiring documentation.
• Relays, fuses, sensor connectors, injector connectors, ignition-coil connectors, wideband sensor connector, and other application-specific termination components are sold separately unless otherwise stated.

Emissions and Competition-Use Notice

Unless specifically identified as emissions-legal for the applicable vehicle and application, this product is intended for sanctioned competition, off-road, or other non-emissions-controlled use. Installation or use on an emissions-controlled vehicle operated on public roads may violate federal, state, or local law.
