Unlock More Inputs & Outputs From Your Link ECU

Need to add fuel pressure, oil pressure, flex fuel, boost control, switches, or additional sensors to your Link ECU setup?

The Link ECU XS Expansion Loom (XSL) makes it easy to access additional inputs and outputs available through the expansion connector on compatible Link ECUs.

Instead of cutting into your factory wiring harness or trying to build an expansion connector from scratch, the XSL gives you a pre-terminated connector with color-coded flying leads ready to wire into your vehicle.

Perfect for Adding More Sensors

As your build gets more serious, you usually need more information going into the ECU.

The XS Expansion Loom provides a clean way to add compatible sensors and functions such as:

• Fuel pressure sensor
• Oil pressure sensor
• Flex fuel / ethanol content sensor
• Intake air temperature sensor
• Additional temperature sensors
• Additional pressure sensors
• Boost control
• Launch control switches
• Map switching
• External switches
• Auxiliary inputs
• Auxiliary outputs
• Additional engine protection functions

Available functions will depend on your specific Link ECU and configuration.

Ideal for Fuel & Oil Pressure Protection

If you're building a turbocharged, high-horsepower, or race application, adding fuel and oil pressure sensors is one of the smartest upgrades you can make.

With the appropriate sensors connected to your Link ECU, you can monitor and datalog critical engine information.

Your tuner can then configure protection strategies based on the available ECU functions and sensor data.

That means your ECU can do more than just control the engine—it can help identify a problem before it becomes an expensive failure.

Great for Flex Fuel Builds

Want to run ethanol content monitoring?

The XS Expansion Loom can provide access to the appropriate ECU connections on compatible applications, allowing a flex-fuel sensor to be integrated into your Link ECU setup.

Once properly configured, your ECU can use ethanol-content information as part of your tuning strategy.

Pre-Terminated Connector

There's no need to source the expansion connector and individual terminals separately.

The XSL comes with the ECU-side connector already terminated, while the opposite ends are left as flying leads for your installer to connect to the required sensors, switches, or devices.

This gives you the flexibility of a custom harness without having to build the ECU connector yourself.

Your Build Evolved. Your ECU Wiring Should Too.

Maybe your car started with a basic engine swap and a few bolt-ons.

Now you've added a turbo, upgraded fuel system, flex fuel, pressure sensors, boost control, and additional engine protection.

The Link ECU XS Expansion Loom (XSL) gives you a clean way to expand your engine-management system as the build grows.

More sensors. More control. More data. Better protection.

Important Compatibility Note

The XS Expansion Loom (XSL) is designed for compatible Link ECU applications equipped with the appropriate expansion connector. Available inputs, outputs, wire functions, and supported features vary by ECU model.

Always verify compatibility and follow the pinout for your specific Link ECU before wiring the loom.
