    So I got this kit from Amazon over Christmas


    I just tried to put it in today using the usual OEM instructions. It appears to be from a company called Winjet. 2011-2014 Toyota Prius V Fog lights - (Clear) - (Wiring kit Included)
    However the OEM instructions wiring does not match up in color and wires. The lights fit perfect, and the wiring harness appears to be designed to fit the Prius V perfect. The question though comes from there only being a single yellow wire to stick through to the inside.

    Also please note in the small print on the listing at Amazon...."Instructions not included" - insert face / palm here.

    The biggest confusion for me is that back of the button on the dash has only 3 wires. One is the yellow which would seamingly go to the one that came through the firewall. One is black and has a ground ring on it and the last is red and has a sticker saying ignition. Would that be the same as pin 32 found on other kits?

    Update.
    The wiring in my kit appears to be close to the link I found. However. I tried to t-tap into wire #32. This caused the fog light switch to power up even when the car was turned off. I turned on the light and then tried to hit the fog light. The light on the switch went out and no fog lights. Dad and me verified the plug is getting power in the switch box via 12v blades and the wiring is all got good contacts. So we decided to go for the field goal, so to speak, and t-taped into wire #22. Again this one caused the switch to light up right away, even when car turned off. Not a good sign. But this time when I turned on the parking lights and then headlights. No fog lights lit however when I hit the fog light switch, my bright lights came on. DOH! So I am to a frustrated point. I have removed the T-tap connections for now and currently thinking about ordering the correct wiring harness. The t-taps area already in place and the fogs are already mounted so installation should be pretty easy to pull the old wiring harness out and put in the correct one.

    Anyone have suggestions or best place to order just the harness?

    Sounds like you need to connect the red wire from the switch to a wire or fuse circuit that is only powered when in Ready mode. I tapped the fuse designated for the seat heater circuit for my foglight switch installation.

    The switch is both illuminated and passing power to the relay coil when the switch is in the On position. When in the Off position, the switch should only be illuminated when in Ready mode.

    Thanks xliderider.
    Just trying to track down which wire that would be. So far every wiring diagram I can find is the OEM wiring which this Winjet kit did not follow. I know I don't have seat heaters per it being version 3 so that should be available.

    Looking at the manual and the cover to the box, it appears it was slot 4 which was a 10a. I purchased a add-a-circuit and put in the 10a fuse that came with the AaC and put it to the red wire. It did not work, so I then tried the 6th slot which was the other seat. Failed too. Not to be defeated, I decided to look at the AaC to see if I was using it correctly. Yes. I, a man, looked at instructions for more than the pictures. Seems the device your adding has to be in slot B of the AaC and it clearly states that if the device does not power, flip around the unit. Made these corrections and NOW IT WORKS!! Lights come on when car is running, button lights with car being on which is not a big deal. Push the button and the lights come on with the green light coming on the button to indicate the lights on. It does not turn off automatically when high beams are hit however it does work which makes me happy.

    Thank xliderider for the tip. I was about ready to order the wiring harness, or even a kit with promised not to be from Winjet. ;)

    Thanks, that wiring worked for me too but I ran into a problem with the switch that would not stay in the on position. As long as I held it in it would light up the fogs but go off as soon as I released the button. I removed the switch from the panel and and found that if I squeezed gently on the back cover the switch would stay on. I took off the cover by carefully prying upwards while releasing the retaining tabs. To fix it I cut a rectangular shim out of a water bottle and put it on top of the circuit board. After I replaced the cover the switch will stay in when pressed like it should. Cheap parts sometimes respond to cheap fixes
