Description
This plug-and-play harness connects to the vehicle diagnostic port and provides 12V power to run the system, so you can bench test, program, and diagnose any supported ECM off the truck.
This version reads:
– SAE J1708 / J1587 protocol
– SAE J1939 protocol – CAN: 250K
Add the ECM jumper harness for your specific engine — the jumper connects the base to the ECM. One base harness works with every ECM jumper (Cummins, Detroit, Paccar and more). Works with diagnostic software such as JPRO, Calterm, INSITE, and Davie.
Also known as a bench calibration base or diagnostic bench harness. This is the connector 8 pin version.
Need J1939 CAN at 500K or 667K? See our 12 pin base bench harness.
