Group LED Flash Pattern Programming

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 LEDs. Refer to the Explorer, Taurus Police Interceptor Modifier Guide for specific flashing LED patterns.
  1. Activate the flashing LEDs in the group to be programmed.
  2. Locate the pattern programming circuits at inline C4231. To change the flashing pattern:
    • For park/turn/warn, grille, front corner and tail lamp flashing 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  .
    • For high mount and decklid flashing LEDs:
      • To cycle forward to the next pattern, connect 12 volts to pin 1 of inline C4231 for less than 1 second  .
      • To cycle back to the previous pattern, connect 12 volts to pin 1 of inline C4231 for greater than 1 second  .
