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.
Diesel Laptops Bypass Breakout Main Programming Cable
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 recomend 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.
- 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.
