Why would you need an ECM breakout harness?
- Most OEMs recommend NOT programming the vehicle through the dash connector, but instead go directly to the ECM. These are the perfect programming cables for such a project.
- You are having issues with the diagnostic port on your commercial truck, and wish to bypass the vehicle wiring and go directly to the ECM.
- You have an ECM that is not installed on the truck and wish to do programming or modifications on the workbench.
