Diesel Laptops Bypass Breakout Cable for Cummins CM2350



Diesel Laptops Bypass Breakout Cable for Cummins CM2350

This is a bypass breakout cable used to connect to Cummins CM2350 engines.


  • All cables are tested on live ECMs and validated before shipping.
  • Professional, quality manufactured cable made in the USA.
  • 12 month warranty.

This cable is used on Cummins ECMs that are classified as CM2350. This bypass harness is used to connect directly to the ECM instead of going through the vehicle dash connector.

The Cummins ECMs with the CM2350 system have been used in production 2013 through the current model year. This covers almost all Cummins on-highway engines, including ISB6.7, ISC8.3, ISL9, ISX12, ISX15, ISV5.0, and more. If your engine is a CM2350 this cable will fit. If you are unsure if this is the correct cable for you, please contact us so we can look it up for you.

Note: This cable also requires our Main Bypass Programming Cable to connect to the ECM. Our unique design allows you to purchase this main cable first, then purchase the "ends" that you need to connect to various ECMs.

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.

Diesel Laptops Bypass Breakout Cable for Cummins CM2350

Anthony Mendoza
Does what it needs to do.

Not much to review. I'm happy with all my diesel laptop products so far. Cable hooks up directly to the ECM. Majority of the time I use my bypass cables to verify if an ECM is completely shot or if I'm having harness issues.
