This Engine Control Module (ECM) programming harness is to be used with any of our BenchForce™ PowerBlock switch assemblies to reprogram P12 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 P12 ECM programming harness requires Pass-Through Harness. The BenchForce™ PowerBlock uses EFI# 100-01072. Pass-Through Harness sold separately.

P12 ECMs Contain Internal CAN Termination
This simply means that an external CAN termination resistor is not required and that the P12 ECM can be programmed on the benchtop with a direct connection to the OBD2 Switch Assembly using a Pass-Through Harness. The BenchForce™ PowerBlock uses EFI# 100-01072.

* While this P12 ECM programming harness is compatible with all P12 ECM equipped vehicles listed above, there may be many P12 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.
