Nexus V8 Junior Timer (EV1)Secondary Injector Breakout

The Haltech Nexus V8 Junior Timer EV1 Secondary Injector Breakout expands your Nexus R5 ECU's capability by adding controlled secondary injector staging. This breakout harness provides timed activation of additional EV1 connector injectors, enabling greater fuelling capacity for forced induction or high-output naturally aspirated V8 applications. Ideal for tuners needing to manage both primary and secondary injector banks with precision, it integrates cleanly into existing Nexus wiring while maintaining Haltech's exacting build quality. Essential hardware for builds pushing beyond single-injector fuelling limits.
