This is the cable to use with the MX ECM to bench

flash and test ECM’s.

You can use this to test an ECM by taking the truck wiring

out of the picture. 

     And also run the engine with no truck hooked

or test stand operation.

This harness has a toggle switch to simulate the ignition switch.

It is fuse protected

As all my harnesses I carry a stock for immediate shipping.

I ship on a daily basis.


  I also have listings for bench harnesses for Caterpillar ECM's.

And Paccar MX engines.

Detroit engines.

I have been a diesel tech for over 30 years.

I make up all sorts of diagnostic tools for electronics.

Any questions please ask.
