Nexus V8 Junior Timer (EV1) Injector Primary Breakout

Overview

The Nexus V8 Junior Timer Injector Primary Breakout transforms your Haltech Nexus R5 harness for seamless EV1 injector integration. Purpose-built for high-performance V8 builds running EV1-style injectors, this breakout eliminates wiring complexity and ensures reliable fuel delivery under extreme conditions.

Technical Specifications

• Part Number: HT-186000
• Connector Type: EV1 Style Injector Interface
• Compatibility: Nexus R5 Universal V8 Terminated Harness (HT-186200)
• Channel Count: 8-Channel Primary Injector Control

Why You Need This

EV1 injectors remain the gold standard for serious V8 builds — from LS swaps pushing serious power to methanol-fed drag motors requiring massive flow rates. The challenge is connecting these industry-standard injectors to your Nexus R5 harness without butchering looms or creating voltage drop issues. This breakout solves that problem completely.

Without proper interface hardware, you're left splicing connections, creating potential failure points that kill engines at the worst possible moment. We've seen too many builds compromised by dodgy injector connections causing lean conditions under boost. This breakout maintains the signal integrity and current handling your high-flow injectors demand, whether you're running 1000cc units in a twin-turbo LS or 2000cc monsters in a methanol Pro Mod motor. The plug-and-play design means reliable connections every time, no guesswork, no voltage drops that cost horsepower or engines.

ECU & System Compatibility

Designed specifically for use with the Haltech Nexus R5 ECU and the Universal V8 Terminated Harness (HT-186200). This breakout integrates seamlessly with the Nexus R5's advanced injection control algorithms, supporting both sequential and batch fire injection strategies across all eight cylinders.
