A Deutsch DTM-4 connector loom that plugs the RDM-7 directly into your ECU. The DTM-4 end goes to the ECU; the dash end is pre-terminated and slipped into the RDM-7's terminal — and it ships pre-installed on every RDM-7 unit. This product page is for replacements, spares, and adapter-included orders. Power and CAN communications all run on the single DTM-4 connector. One plug to the ECU, one cable to the dash. Done. Key Features Direct fit on Haltech ECUs. Haltech runs Deutsch DTM-4 natively on its CAN ports — this harness plugs straight in. No adapter needed. Works with Link via Link's own DTM-4 adapter. Link sells a CANPCB / CAN-DTM adapter directly — pair this harness with that adapter for a clean Link install. Power + CAN on one plug. 12 V supply, ground, CAN High, and CAN Low all carried on the single DTM-4 connector. No separate power feed, no spliced CAN tap. RDM-7 end is pre-terminated. Stripped, ferruled, and ready to slip into the RDM-7's screw-terminal block. Ships pre-installed on new units. Sealed automotive connector. The DTM-4 is the same connector family Haltech, MoTeC and most motorsport ECUs use — vibration, heat, and weather tolerant. What It Does This harness is the cable between your ECU and the RDM-7. The DTM-4 end mates with the ECU (directly on Haltech, via the Link DTM-4 adapter on Link). The other end is stripped and seated in the RDM-7's terminal block. Plug it into the ECU, power up the dash, and CAN data starts flowing. Specifications ECU connector Deutsch DTM-4, 4-pin, sealed Dash connector Pre-stripped and installed with purchase of RDM-7 Dash.
