Compatibility
What matters is the ECM type, not the engine series or vehicle brand.This cable harness is designed for the Cummins ECM CM2670 and CM2880 with the 94+96-pins connector. Cojali does not document engine or vehicle coverage for these isolation harnesses: there is no list of engine series or vehicle brands to check whether the harness will work in your situation. Therefore, verify the ECM type and the pin count yourself before ordering.
- What does matter: The ECM type (Cummins ECM CM2670 and CM2880) and the pin count of the ECM connector (94+96-pins).
- What doesn't matter: The engine series, vehicle brand, and model year; no information is documented for these harnesses on those points.
- You need to check: Read the control unit type from the nameplate and count the pins on the connector.
- If you're unsure: Provide us with the ECM type and pin count, and we'll help you determine which version you need.
