Cummins Base Harness

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 pin 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. I sell the adapters separately.
