    Sorry if this is the wrong place to post. I purchase some blacked out taillights for my tundra (wolfstorm). I saw the warnings that the harness may not fit a platinum so I reached out to wolfstorm and they assured me they did. Well, they don't. Apparently the blinker harness on a platinum is different? The instructional video and the tail light itself have a 3 wire harness for the the blinker and my tundra only two. It seems like 3 is the norm. Is there an adapter I can use or can I just splice the wires together? If I can splice, which two do I combine or do I just leave one out? My harness has a yellow wire and a white one with a black line. The new one has green, black, and red. Thanks for any advice you may have.

    The Platinum tail lights are no different than any other Tundra.
    They would all have a 2 wire rear turn signal, hot and ground.
    The brake light, however, would be a 3 wire for the brake, parking light, and ground.
    Reverse lights, 2 wires, hot and ground.
    Did it not come with some kind of adapter for the turn signal plug?
    Or does the wolfstorm turn signal socket not fit with your OEM turn signal plug?

    I looked on their website and couldn't find any instruction manuals.
    Maybe you could post some pics of what you have and/or a link to the installation video.

    The plug position is different on the aftermarket light..
    Your 3-wire plug plugs into the top wire, and your 2 wire turn signal plugs into the middle, and your OEM backup light (bulb and all) goes in the hole on the bottom where the arrow sticker is..
    .

    Is that correct?
    I would get a decent brighter 7440 LED bulb and use it for your reverse lights..

    There is a ton of them on Amazon.

    I thought that at first as well, but both of the plugs on the tundra are two wire. I did get the leds as you mentioned.

    On your OEM tail light:
    Your bottom brake/parking light has 3 wires on it.
    Your turn signal has 2
    Your reverse light has 2, but that doesn't matter because they don't 'plug in' to the aftermarket light.
    Your OEM rev light goes into the light.



    Are your plugs not like the video I posted?
    That is OEM..

    What you had in your hand in the pic above is the left turn signal.
    Yellow wire with white and black stripe.

    Your brake parking light will have 3 wires

    The one on the left is your turn signal light, plug slots/tabs in the middle.
    The one in the middle is your rev light it needs the socket and bulb on it, plug slots/tabs are offset.
    BUT the one on the right (with the socket still on it) is your brake parking light, the 3-wire plug.
    Pull that socket off and you're good to go.:thumbsup:

    These are the sockets that you removed.
    I only have these laying around because I replaced all my tail lights with Hotshot harnesses and LED bulbs..:cool:
