Look at the air inlet where it attaches to the cylinder head. It should have two good sized cables hooked to grid heaters that are in the airflow just before the head. The grid heaters cycle on, light shows on dash, wait for it to go off turn key and Cummins music starts.
It's also why starting fluid is a huge no no on this engine.
