v5 LED Sequencer


These units require 12v power/ground to operate. Typically, sequencer power is wired into fused constant 12v on the vehicle so various functions work when the car is off (like turn signals for hazards or show mode). The inputs for various sequencer functions are 12v, and the outputs to control the LEDs operate on the ground.

If you ordered your sequencers pre-programmed; on headlight programming: switchback is enabled, and brake input is disabled. On taillight programming: switchback is disabled, running lights run at “dim” setting, and brake input is enabled.


Soldering iron, solder, 3rd hand (optional), 22-26 gauge wire, LEDs/LED arrays within tolerances, 12v switch (wired or wireless) to activate show mode, add-a-fuses to power boards and car on/off function (fuse style to match your car), grounding strap (highly recommended to minimize potential damage to output channels from static charge)

LED Sequencer wiring tutorial

On-car wiring explanation

12v – Connect this to 12v constant power
Gnd – Connect this to any vehicle grouund
In1 – Brake signal 12v input
In2 – Turn signal 12v input
In3 – Show mode 12v input
In4 – Startup/Shutdown signal 12v input
(alternatively can function as a secondary show mode 12v input)
In5 – Parking/running lights signal input
Programming header – the Pickit3 connects here

Any 12v Connection point can be used for output

Ground channel output order:


  1. Download and review the User Manual (this is important to understand the maximum tolerances this board can handle)
  2.  Solder grounds of LEDs/LED arrays to the ground outputs on the sequencer
  3. Solder main power/main ground/inputs to operate the board
  4. Activate various 12v inputs to test functions
    1. If your unit does nothing, it may be blank and need programming
  5. To re-program the unit, you will need a Pickit3 to interface with the programming pins (identified in the user manual)
    1. You optionally can extend the programming pins out of the housing to re-program the boards later
