IO16 Universal Wire in harness 2.6M (8.5)

Overview

The Haltech IO16 Universal Wire-in Harness transforms your Nexus or Elite ECU into a comprehensive control system by adding 16 configurable input/output channels via CAN communication. Essential for complex builds requiring additional sensor inputs, relay outputs, or switched circuits beyond your ECU's native capacity.

Technical Specifications

• Part Number: HT-180000
• Length: 2.6 metres (8.5 feet)
• Channels: 16 user-configurable I/O
• Communication: Haltech CAN protocol
• Wire Gauge: Automotive grade multi-core
• Termination: Bare wire ends for custom integration

Why You Need This

Modern engine swaps and performance builds quickly exhaust an ECU's native I/O capacity. Running a twin-turbo LS swap? You'll need inputs for multiple temperature sensors, pressure sensors, and outputs for wastegate solenoids, boost controllers, and cooling fans. The IO16 expansion solves this elegantly through Haltech's CAN network, avoiding the complexity and reliability issues of aftermarket relay boxes or secondary control modules.

This wire-in harness suits fabricators building custom installations where plug-and-play solutions don't fit. Popular applications include track cars requiring additional data logging inputs, drag cars with complex launch control systems, and street builds integrating factory comfort features. The 2.6-metre length provides flexibility for engine bay to dashboard runs or distributed sensor placement in larger vehicles. Each channel handles both analogue inputs (0-5V sensors) and digital outputs (12V switched), configured through ESP software.

ECU & System Compatibility

Compatible with all Haltech Nexus R3, R5, and Rebel ECUs, plus the complete Elite range including 550, 750, 1000, 1500, 2000, and 2500 models. Requires a Nexus IO16 expansion module (sold separately) to function. The CAN communication integrates seamlessly with existing Haltech CAN devices including wideband controllers, dash displays, and other expansion modules.

Complete Your Build

This harness requires a Nexus IO16 expansion module to function — contact our technical team for the complete package pricing and installation guidance. Most customers building complex systems also benefit from additional CAN termination resistors and our custom connector kits for professional finishing. Our workshop regularly installs these systems and can advise on optimal channel allocation for your specific application, ensuring you maximise the expansion capability without conflicts.
