Compatibility
The ECM type is what matters, not the engine series or vehicle make.This harness is designed for the Cummins ECM CM2150 with the 4+60-pins connector. For these isolation harnesses, no engine or vehicle coverage is specified: there is no list of engine series or vehicle makes to check whether the harness suits your application. What counts is the control unit nameplate and the number of pins on the connector.
- What matters: The ECM type (Cummins ECM CM2150) and the number of pins on the ECM connector (4+60-pins).
- What doesn't matter: The engine series, vehicle make and year of manufacture; these are not specified for this harness.
- Check yourself: Read the control unit type from the nameplate and count the pins on the connector.
- Recognisable by the connector: If there is a separate 4-pin connection alongside the 60-pin main block, this is the correct version; if it's missing, you need the JDCM2250.
