Haltech Elite 1000 / Elite 1500 Terminated Main Harness – Mazda 13B | EV1 Injector Connector | Main Harness Only

The Haltech Elite 1000 / Elite 1500 Terminated Main Harness for the Mazda 13B with EV1 injector connectors is a pre-terminated, plug-and-play main wiring harness engineered for use with the Haltech Elite 1000 or Elite 1500 ECU on Mazda 13B rotary engine applications using EV1-style fuel injector connectors. This is the main harness only — sub-harnesses (ignition, injector extension, sensor sub-harnesses) are not included and must be sourced separately as required for your specific 13B build configuration. Haltech is one of the most respected standalone ECU and wiring harness brands in the performance aftermarket — an Australian brand with a strong following among rotary engine builders and performance enthusiasts globally.

Key Features:

• Pre-terminated main harness — factory-terminated wiring harness for the Haltech Elite 1000 / Elite 1500 ECU — eliminates the need to fabricate a custom main harness from scratch for the 13B application
• Mazda 13B specific — engineered for the Mazda 13B rotary engine — correct connector types, wire lengths, and circuit assignments for the 13B's sensor and actuator layout
• EV1 injector connectors — terminated with EV1-style fuel injector connectors — correct for 13B builds using EV1-compatible fuel injectors — verify your specific injector connector type before ordering
• Compatible with Elite 1000 and Elite 1500 — correct for both the Haltech Elite 1000 and Elite 1500 ECU platforms — verify your specific ECU model before ordering
• Main harness only — this harness provides the main ECU-to-engine wiring — sub-harnesses for ignition, injector extensions, and other functions are not included and must be sourced separately
• Haltech quality — manufactured by Haltech, one of the most respected standalone ECU and harness brands in the performance aftermarket

Main Harness Only — What This Means:

This listing is for the terminated main harness only — sub-harnesses are not included. A complete Haltech Elite 1000/1500 wiring installation for the Mazda 13B typically requires the main harness plus additional sub-harnesses depending on the specific build configuration — ignition sub-harnesses, injector sub-harnesses, sensor sub-harnesses, and other application-specific wiring. The main harness provides the core ECU-to-engine wiring backbone, but the complete harness set required for your specific 13B build will depend on your ignition system, injector configuration, sensor setup, and other build-specific factors. Consult Haltech's product documentation and your ECU installer to determine the complete harness set required for your specific 13B Elite 1000/1500 installation before ordering.

EV1 Injector Connectors — Verify Before Ordering:

This harness is terminated with EV1-style fuel injector connectors — the older, larger rectangular injector connector used on many performance injectors and OEM applications. EV1 connectors are compatible with a wide range of performance injectors from brands including Bosch, Siemens Deka, RC Engineering, and others. If your 13B build uses injectors with EV6 (USCAR) connectors — the smaller, more modern connector used on many current-generation performance injectors — this harness is not the correct choice. Verify your specific injector connector type before ordering.

Elite 1000 vs. Elite 1500 — Harness Compatibility:

This terminated main harness is compatible with both the Haltech Elite 1000 and Elite 1500 ECU platforms. The Elite 1000 and Elite 1500 share the same main harness connector configuration — the difference between the two ECUs is in their internal feature set and I/O count, not their harness interface. Verify your specific Haltech Elite ECU model (1000 or 1500) before ordering to confirm harness compatibility.
