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.

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.
