This Engine Control Module (ECM) programming harness is to be used with any of our OBD2 switch assemblies to reprogram E41 ECMs outside of the vehicle.

OBD2 Switch Assembly Pass-Through Harness
ECU harnesses connect to the OBD2 switch assembly through a short pass-through harness. This E41 ECM programming harness requires Pass-Through Harness for GM EFI# 100-01032. Pass-Through Harness sold separately.

E41 ECMs Contain Internal CAN Termination
This simply means that an external CAN termination resistor is not required and that the E41 ECM can be programmed on the benchtop with a direct connection to the OBD2 Switch Assembly using Pass-Through Harness for GM, EFI# 100-01032.

* While this E41 ECM programming harness is compatible with all E41 ECM equipped vehicles listed above, there may be many E41 ECM service numbers. The ECM service number should match the vehicle service calibration to avoid potential damage to the ECM.

Caution should be taken to ensure ECM/program compatibility before service programming.
