Electrical Diagrams
CAUTION:^ Any Auxiliary Warning Lights, controlled by the Lighting Control Module (LCM), need diode protection to prevent current spike damage to the LCM.
^ When installing aftermarket equipment, avoid using fasteners that are too long for the application or in an area which might damage Vehicle components, i.e. wiring, brake lines, fuel tank and lines, powertrain components, exhaust system, suspension, etc.
^ Also, DO NOT make electrical connectors into the Powertrain Control Module or PCM harness. Connecting into this system may affect engine and transmission operation.
^ As an example: Connection of aftermarket electrical equipment into the brake light circuit or any other circuit which is connected to the Powertrain Control Module (PCM), anti-lock brake computer, air bag system or any other Vehicle system will cause malfunction.
