Troubleshooting wiring harness and connector hidden concerns
The illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are
hidden and can only be discovered by a physical evaluation as shown in each illustration.
NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be
replaced, they must be replaced with a gold plated terminal.
