INSTALLATION INSTRUCTIONS

I. Disconnect the batteries

For specific instructions and precautionary steps regarding

recommendations for battery disconnection, refer to the

“Workshop Manual” for 2004 F250/350/450/550 vehicles,

published by Ford Motor Company. This manual also contains

battery-related precautionary steps regarding the Supplementary

Restraint System (SRS) or air bag system. Failure to read and

observe factory-recommended instructions may result in personal

injury or property damage.

NOTE: When the battery is

disconnected and re-connected, some abnormal drive

symptoms may occur while the vehicle relearns its adaptive

strategy. The vehicle may need to be driven to re-learn its

adaptive strategy.
