Always inspect harness connectors that are involved in circuit. Poor
Normal
connections can often be the cause of an electrical circuit problem.
Verify that all connections in circuit are clean, secure, and connections
are in good condition. If a problem with connection is found, correct
problem and verify diagnostic code is active before performing this
procedure.
Tag wiring harnesses to aid installation.
