Haltech NEXUS IO16 Input/Output Expander w/Universal 8.5ft Wire-In Harness

With the Haltech NEXUS IO16 Input/Output Expander, you get a universal 8.5-foot wire-in harness. This expander is designed to add more inputs and outputs to your Haltech NEXUS ECU, giving you greater flexibility for custom setups. If you're building a complex system or need to integrate more sensors and actuators than your primary ECU can handle, this expander is a solid choice.

The IO16 module itself is built to integrate seamlessly with your existing Haltech NEXUS system. It provides 16 additional channels that can be configured as either analog or digital inputs, or as outputs. This means you can connect more temperature sensors, pressure sensors, speed sensors, or even control additional cooling fans, fuel pumps, or other accessories directly through your ECU. The included 8.5-foot harness is universal, meaning it's designed to be wired into whatever custom application you have in mind, offering a good length for routing flexibility.

When you're working with advanced engine management systems like the Haltech NEXUS, having the ability to expand your system's capabilities is key. This expander is a well-built component that allows for a more comprehensive data acquisition and control setup. Keep in mind that this unit is not CARB approved and cannot be shipped to California.
