Overview Purpose-built CAN communication cable engineered for Haltech Elite ECU systems requiring reliable data transmission between modules. This 300mm DTM-4 to DTM-4 cable delivers the critical backbone for multi-ECU setups, wideband controller integration, and advanced engine management communication where standard lengths don't fit your installation requirements. Technical Specifications Part Number: HT-130022 Length: 300mm (12") Connector Type: DTM-4 to DTM-4 Application: Haltech Elite CAN Bus Communication Wire Gauge: CAN-compliant twisted pair Operating Temperature: Engine bay rated Why You Need This CAN bus communication is the nervous system of modern engine management, and cable length matters more than most builders realise. Too long and you introduce resistance that can cause communication dropouts under vibration. Too short and you're fighting routing constraints that create stress points and potential failures. This 300mm cable hits the sweet spot for most engine bay applications where you need to connect Elite ECUs to wideband controllers, secondary ECUs in twin-engine setups, or data logging modules in confined spaces. We see this cable specification regularly in LS swap builds where the ECU mounting location demands precise routing around headers and brake lines, RB26 twin-turbo setups requiring wideband controller placement away from exhaust heat, and motorsport applications where vibration resistance is critical. The DTM-4 connectors provide the secure, weatherproof connection that standard automotive connectors simply can't match in high-performance environments. Without proper CAN communication, you lose critical engine protection functions, wideband feedback, and data logging capabilities that modern tuning demands. ECU & System Compatibility Designed specifically for Haltech Elite 550, 750, 1000, 1500, 2000, and 2500 ECU families, plus Nexus R3 and R5 systems where DTM-4 CAN connections are specified. Essential for integrating WB1 and WB2 wideband controllers, secondary Elite ECUs, and compatible data acquisition systems.
