Activation 

1. WARNING: Police Package warning lights are a high-intensity Light-Emitting Diode (LED) type. Do not stare directly at these lights, as doing so may cause temporary blindness and/or eye damage. Failure to follow this instruction may result in personal injury.
   NOTE: When cycling through flash patterns, most flash patterns include an off/on pattern followed by an inverse on/off pattern. Setting the LED on one side to the on/off and the other to off/on creates the alternating pattern effect which should not be confused with synchronization which applies to the pattern timing between LED groups. For proper synchronization, the correct flash patterns must be selected for the individual flashing Light Emitting Diodes (LEDs). Refer to the Utility Police Interceptor Modifier Guide for specific flashing LED patterns.

   Activate the flashing Light Emitting Diodes (LEDs) in the group to be programmed.

2. Locate the pattern programming circuits at inline C4231.

3. To change the flashing pattern for grille, exterior mirror and, if equipped, front auxiliary flashing Light Emitting Diodes (LEDs):
   • To cycle forward to the next pattern, connect 12 volts to pin 2 of inline C4231 for less than 1 second.
   • To cycle back to the previous pattern, connect 12 volts to pin 2 of inline C4231 for greater than 1 second.

4. To change the flashing pattern for rear lamp, high mount and decklid (underside) flashing Light Emitting Diodes (LEDs):
   • To cycle forward to the next pattern, connect 12 volts to pin 2 of inline C4231 for less than 1 second.
   • To cycle back to the previous pattern, connect 12 volts to pin 2 of inline C4231 for greater than 1 second.
