Central Control Module: Diagnostic Aids
General Electrical Precautions
^ Note the following items when servicing the electrical system.
^
Do not alter the wiring or electrical equipment in any way; this may damage the vehicle or cause a fire from short-circuiting a circuit oroverloading it.
Removal Of Battery Cable
^ The negative (-) battery cable must be removed first and installed last.
Replacing Of Fuses
^ Do not replace with fuses exceeding specified capacity.
Securing Harness
CAUTION
^
Be sure that the ignition and other switches are off before disconnecting or connecting the battery cables.Failure to do so may damage the semiconductor components.
^ Secure harnesses with provided clamps to take up slack.

and Instructions > Page 21
Millenia V6-2255cc 2.3L DOHC (1995)
Protection Of Harness
CAUTION
^ Replacing a fuse with one of a larger capacity than designated may damage components or cause a fire.
^ Tape areas of the harness that may rub or bump against sharp edges to protect it from damage.
^ When mounting components, be sure the harness is not caught or damaged.
Page 28
Handling Of Electrical Components
CAUTION
^ Clamp all harnesses near vibrating components (for example, the engine) to remove slack and to prevent contact resulting from vibration.
^ Do not handle electrical components roughly or drop them.
Heat Sensitive Parts
^
Disconnect heat- sensitive parts (for example, relays and ECU) when performing maintenance (such as welding) where temperatures may exceed .8OC (176F)
Installation
^ Make sure that the connectors are securely connected when installed.
