This is the main cable harness used to connect directly to a commercial truck ECM.
Features:
- All cables are tested on live ECMs and validated before shipping.
- Professional, quality manufactured cable made in the USA.
- 12 month warranty on all components.
This is our "main" cable that you can use to build your own unique bypass/breakout cable to connect directly to a commercial truck ECM. If you purchase any of our bypass cables individually, you will need this cable as well. Our bypass cables are a 2-piece system, with each one needing this one.
This main harness connects to a power source and provides a 9 pin connector that is detachable. This allows you to purchase the ECM connectors you need, instead of having to purchase a completely new harness.
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.
