    I need some help in wiring a led light bar for my 06 Tacoma. The question is if I hooked it up right. The reason I am asking I have the led green light on the switch is on all the time. Can’t figure out on how to turn it off. And only come on when I turn on With the tail light. I have looked at other YouTube videos and photos and the wire from the switch wires are not the same that I have.. I even read thru threads and still can’t figure it out. Her are some pictures I took.


    Here I have three wires blue,black,and white from relay from light bar. The switch wires are black,blue,green,and red.. so I put black to black,blue to blue and it is hot all the time,white to green,and red to add a fuse which I put in the tail light fuse..

    But when I hook everything up the switch works great and led bar is switch on and off with the tail lights are on. BUT THE GREEN LED ON THE SWITCH WILL NOT GO OUT WHEN THE TAIL LIGHTS ARE OFF.. B2031913-057C-40FE-8133-0B8B588632A1.jpg
    If there is anything I can wire different please let me know. I would like the green light go off when the tail lights go off

    Blue (+) & black is your switch illumination.
    Green to relay.
    Red from fused source.
    Blue should go to Tail circuit.
    You still have a hot switch due to light bar harness always hot source. Meaning if left on you'll get battery drain

    Black is ground.
    Blue should connect to a Dash Lighting Circuit (this switch has a back-light that is ON when your dash lights are ON).
    Green is to control the relay.
    Red should connect to ACC Power Source.

    When the switch is turned ON, the connection is made between the red and the green. The picture of the light bar (on the switch) should illuminate to show that your lights are ON.

    It did not work. There is Constant power all the time. The switch light is on all the time. Here is the picture of what I did.

    Then you are seem to be connected to an 'always on' circuit, when you should be on a switched (ACC) circuit

    Or you have the key in the on position when checking your work. (no insult, just a thought)

    You need to hook up the illumination wire on the switch to an illumination source from the truck. It should not be connected to your light bar.


    ETA: From the switch- The Green wire goes to the battery, the red w/yellow stripe closest to green wire goes out to the relay; the black wire connects to the ground, while the red w/yellow stripe closest to black goes to the dash illumination.

    Both of your black wires should be connected to ground rather than butt-connected together.

    I don't think you fully understand the function of this switch. When I researched this switch, I read that it has 2 LED inside the switch.

    1 LED is for Dash Illumination (switch lettering "LED LIGHT BAR")
    1 LED is to show that the lightbar has been turned ON. (Picture of light bar on switch)

    If this is correct, then you need:
    1) A power source from the Dash Lights (preferred) OR ACC power source. This will give you a "constant ON illumination" when the Ignition switch is in ACC Mode or Run Mode. If you can Tap a Dash Lighting Circuit, then the LED will also Dim when you adjust the brightness of your Dash Lights.

    2) A 2nd power source preferably from an ACC source (but could be directly from the battery). This power source is used to turn ON the relay that supplies power to the lightbar. Using an ACC power source will give you assurance that your lightbar can NOT be inadvertently left ON when you exit the vehicle.

    So what circuit is good to use? the key is not in the ignition or turned turned on, blue wire has constant power to it.

    The Blue Wire need to be connected to Dash Illumination (Preferred) OR a power source that is only on when your key is ON (ACC Power Source). If yo can find a lighting circuit behind the dash, that would be my 1st choice. If you cant, then tye the Blue and Red together. And connect those wires to an ACC Power supply.

    Refer to the above two posts. You have the switch wired completely incorrect.

    Also your relay (the three wire harness in your picture) is wired incorrectly.

    Ground both the black wires (relay and switch). One of the wires from your relay goes to the switch. The other needs a power source and can be connected in parallel with your source power wire for your switch.

    There are 3 separate circuits: led llumination, switch/relay activation, and relay/light bar. Each one has separate power/ground connections.

    LED illuminnation comes from 12v tail light fuse or dash light + to switch (blue wire), and from switch to ground or dash dimmer ground if you want dimming(black wire). The words get power directly, the light bar image led gets power from the switch but both share the same ground, that's why dimming is on the ground side.

    Current to activate relay comes from 12V source to switch(green wire), out to relay(red/yellow), and from relay to ground.

    Current for light bar goes from battery source through relay to light bar and back to battery through ground wire.
