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.
