Daisy-chain Cable for Haltech Multi-Function CAN Gauge

Scalable Data Networks for Professional Cockpits

Modern motorsport instrumentation demands more than a single readout; it requires a comprehensive suite of data delivered instantly to the driver. The Daisy-chain Cable for Haltech Multi-Function CAN Gauge is the architectural keystone for building a multi-gauge array without the wiring nightmare of traditional analog setups. In the past, installing four gauges meant running four sets of power, ground, lighting, and signal wires—a heavy, cluttered mess that invited failure. This precision-engineered DTM-style cable leverages the power of the Controller Area Network (CAN) to link multiple gauges in a series, creating a unified, high-speed data bus. It allows you to expand your dashboard’s capability effortlessly, passing power, ground, and data from one unit to the next with a single, click-in connection.

Engineering Deep-Dive: CAN Bus Topology and Termination

The daisy-chain configuration is the native topology for CAN bus networks. This cable is designed to extend the high-speed differential signal (CAN High and CAN Low) from the ‘Output’ port of one gauge to the ‘Input’ port of the next. Crucially, this maintains the linear structure of the network, which is essential for signal reflection management. In a CAN network, ‘stubs’ or T-taps can cause signal echoes that corrupt data packets. By using this dedicated daisy-chain cable, you ensure the bus remains linear. The cable also carries the 12V power and chassis ground, meaning your entire gauge cluster is powered from a single source point, eliminating ground loops—a common cause of erratic readings and offsetting in sensitive electronics. The connectors are industry-standard DTM-style, known for their superior environmental sealing and positive locking mechanism, ensuring that vibration from stiff suspension or solid engine mounts never interrupts the data stream.

Operational Benefits: The Plug-and-Play Advantage

For the installer, this cable transforms a multi-day dash build into a task measured in minutes. Adding a second gauge to monitor Ethanol Content alongside your Boost gauge? Simply mount the gauge, plug in this daisy-chain cable to the first gauge, and you are live. There is no need to hunt for a new fuse source, splice into ignition wires, or drill through the firewall for a new sensor wire. The data is already on the bus. For the driver, this results in a rock-solid, synchronous display system where all gauges update in perfect unison, providing a cohesive picture of engine health. Whether you are building a dedicated drift car or a street-driven sleeper, the modularity offered by this cable allows your system to grow with your needs.

Fitment and Compatibility

This cable is exclusively designed for the gaugeART / Haltech Multi-Function CAN OLED Gauge series (HT-061010). It is compatible with the Haltech CAN network used by Platinum, Elite, and Nexus series ECUs. It connects the 4-pin rear connectors between two adjacent gauges.

Technical Specifications

Summary & Includes

The HT-061011 Daisy-chain Cable is the essential expansion tool for your Haltech gauge ecosystem. It provides a robust, professional method for linking instruments without the bulk or complexity of individual wiring harnesses.

Includes:

• 1 x Daisy-chain Cable for gaugeART / Haltech CAN Gauge (41-001.11 equivalent)

Technical Note: When daisy-chaining multiple gauges, ensure that you do not exceed the total current capacity of the primary supply wire. For chains of more than 4 gauges, consider a secondary power injection point or consult the Haltech manual.
