CAN Adaptor Loom DTM-4 to JST 5-pin

Plug ‘n’ Play Link ECU to Haltech Device Interface

The CAN Adaptor Loom (DTM-4 to JST 5-pin) is a precision-engineered interface cable designed to connect Haltech CAN accessories directly to Link G4+, G4X, and G4 Plug-In ECUs. Many Link Plug-In boards utilize a compact white 5-pin JST connector for their CAN/Serial communications. This adaptor converts that specific port into the standard Haltech DTM-4 format, enabling seamless integration of Haltech’s advanced display and monitoring technology with Link engine management systems.

Cross-Platform Compatibility Engineering

This cable is the missing link for tuners who prefer the Link Plug-In ECU for engine control but demand the clarity and customization of the Haltech IC-7 Digital Dash or the precision of the WB1/WB2 CAN Wideband. The loom handles the critical pin mapping between the JST standard and the DTM standard, aligning CAN High, CAN Low, Power, and Ground. This eliminates the risk of pinout errors that can damage sensitive transceiver circuits.

Constructed with flexible, high-strand-count wire, this adaptor is designed to route easily inside the ECU case or under the dashboard, relieving strain on the delicate JST board connector. The twisted-pair construction ensures that the high-speed data stream remains robust and immune to noise, even when routed near the ECU’s ignition drivers.

Operational Benefits

• Direct Board Connection: Mates directly to the 5-pin CAN/Serial header found on Link Plug-In ECUs (Honda, Nissan, Toyota, Subaru applications).
• Instant Dash Integration: The easiest way to get a Haltech IC-7 Dash working on a Link-controlled vehicle without cutting wires.
• Safe Power Distribution: Correctly routes the 12V and Ground from the ECU header (where supported) to the CAN device, or provides a breakout for external power if the header is data-only.
• Data Integrity: Professional crimping and correct impedance wire ensure error-free CAN bus communication for real-time telemetry.

Technical Specifications

Includes

• 1 x CAN Adaptor Loom (DTM-4 to JST 5-pin)

Note: Check your Link ECU manual to confirm the location of the CAN/RS232 header. Some older units may require a firmware setting change to enable CAN on this port.
