Main Bypass Breakout Programming Cable

This is our "main" cable that you can use to build your own unique bypass/breakout cable used 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. Why would anyone need an ECM breakout harness? Here are a couple reasons:

• Most OEMs recommend NOT programming the vehicle through the dash connector, but instead go direct 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 direct to the ECM.
• You have an ECM that is not installed on the truck, and wish to do programming or modifications to it on the workbench.

Features:

• Harness length is 24".
• All cables are tested on live ECMs and validated before shipping.
• Professional, quality manufacturing of cables made in the USA.
• 12-month warranty on all components.
