Description
This is the base harness that you use with all Cummins adapters. It has the ignition on/off switch and powers up the correct adapters. It has the standard 9 pins diagnostic connector. The cable is fuse protected. Has a toggle switch to simulate the ignition switch.
You will need the correct adapter for the ECM you want to program and your diagnostic tool.
You can also use this to test an ECM by taking the truck wiring out of the picture. Or for test stand operation.
