Diesel Laptops Bypass Breakout Main Programming Cable

Diesel Laptops Bypass Breakout Main Programming Cable 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.
