Step 1: Insert the splitter wires into the appropriate controller outputs. Use a small flathead screwdriver to tighten down each connection.
Step 2: Run 12v+ and ground from your preferred power source into the input connections on the controller. Use a small flathead screwdriver to tighten down each connection.
Step 3: Connect the LED driver(s) input connection to one of the splitters output connection(s)
Step 4: Splice the yellow wire (Turn signal + input) to the positive wire of the (left or right) turn signal on the vehicle. Splice to black wire to the ground wire of the (left or right) turn signal on the vehicle, or ground it to the frame.
PLEASE NOTE: the ground connection for the turn signals must be different than the ground connection for the controller. The left and right turn signal grounds must also be separate. The ground connection of each turn signal input on the LED drivers MUST be connected in order for the LED boards to function.
Step 5: Connect the LED driver output connection to the LED replacement board input connection. Ensure that the LED driver connected to the (left or right) turn signal is connected to the (left or right) LED replacement board.
PLEASE NOTE: If the LED replacement boards are producing a "washed-out" or faded color output, the white LEDs are on! Turn the white LEDs off in the app by going to the "Warm" settings and clicking the black circle to disable them. The "Warm" settings control the white LEDs on the replacement boards.
