Ford Mustang 1989-1993 Repair Guide



Electronic modules, such as instrument clusters, powertrain controls and sound systems are sensitive to static electricity and can be damaged by static discharges which are below the levels that you can hear snap or detect on your skin. A detectable snap or shock of static electricity is in the 3,000 volt range. Some of these modules can be damaged by a charge of as little as 100 volts.

The following are some basic safeguards to avoid static electrical damage:

Leave the replacement module in its original packing until you are ready to install it.
Avoid touching the module connector pins.
Avoid placing the module on a non-conductive surface.
Use a commercially available static protection kit. These kits contain such things as grounding cords and conductive mats.
