Always inspect harness connectors that are involved in the
circuit. Poor connections can often be the cause of an electrical
circuit problem. Verify that all connections in the circuit are clean
and secure, and connections are in good condition. If a problem
with connection is found, correct the problem and verify
diagnostic code is active before performing this procedure.
Tag wiring harnesses to aid installation.
1. Connect MSD (WP 0016).
Select engine ECM C6.6 D6K.
2. Start and run engine (TM 5-
2410-240-10), and verify
0190-08 is active.
3. Turn ignition switch to OFF
position (TM 5-2410-240-10).
4. Disconnect E-C4 (WP 0018,

5. Turn ignition switch to ON
position (TM 5-2410-240-10).
