MaxxECU STREET 3-Meter Flying-Lead Wiring Harness

MaxxECU STREET 3-Meter Flying-Lead Wiring Harness

Part Number: 1763

The MaxxECU STREET flying-lead harness provides the primary wiring interface between a MaxxECU STREET ECU and the engine, sensors, injectors, ignition system, power distribution, CAN devices, and supporting vehicle systems.

The ECU connector is pre-terminated, while the application side is left as labeled flying leads for custom routing and termination. Thin-wall automotive wire and printed circuit identification simplify installation, diagnosis, and future service.

Key Features

Application Notes

• This harness is intended for universal custom wiring and is not an application-specific terminated engine harness.
• Engine-side sensor, injector, ignition-coil, relay, power-distribution, and auxiliary connectors are not included unless specifically identified.
• The harness is designed for the MaxxECU STREET connector and pinout.
• It should not be assumed compatible with SPORT, RACE, PRO, GEN2, or other MaxxECU models.
• Harness construction varies by revision.
• REV1 harnesses use mostly 3-meter conductors and include a terminated GT150 auxiliary connector.
• REV2 harnesses use 3-meter conductors throughout and do not include a pre-attached GT150 auxiliary connector.
• Confirm the ECU hardware revision and use the corresponding current MaxxECU STREET wiring diagram before terminating the harness.
• Shielded trigger and wideband circuits must be terminated and grounded according to MaxxECU’s wiring documentation.
• Sensor grounds must remain separate from chassis ground and be connected only as specified by MaxxECU.
• Relays, fuses, wideband sensor connector, engine-side connectors, and other application-specific termination components are sold separately unless otherwise stated.
