Nexus Universal V8 – Junior Timer (EV1) Injector Primary Breakout

Modular Harness System: Nexus V8 EV1 Primary Injector Breakout

The Nexus Universal V8 – Junior Timer (EV1) Injector Primary Breakout is the essential link for running EV1-style injectors on the Haltech Nexus Universal V8 Terminated Harness. This primary breakout connects the main 8 injectors of your V8 engine to the ECU. The EV1 connector (Jetronic/Junior Timer) is a staple of the performance industry, used on everything from the legendary Ford 5.0L and GM LS1 to high-flow aftermarket injectors from Injector Dynamics, Bosch, and Siemens. This harness section ensures that you can utilize these high-performance fuel components with the plug-and-play simplicity of the Nexus wiring system, avoiding the need to cut off plugs and re-terminate your brand new harness.

Engineering & Construction

Engineered for reliability, this breakout loom features 8 individual injector branches routed to a central multi-pin connector that mates with the Nexus main trunk. The EV1 connectors are equipped with the standard spring-wire release clip, known for its positive retention. The wiring gauge is optimized for the currents associated with both high and low impedance injectors (assuming the Nexus or an external driver box handles the low-Z load properly—note: Nexus R5 can drive Low-Z directly). The loom is protected by high-temperature braiding, keeping the installation tidy and safe from engine bay hazards.
