Upgrading the OEM fog light switch on a Tacoma 

Thanks for the video man 😍... I bought 3 of these switches to Dubai from ali express for my Toyota fortuner in India. Eager to see if the wiring will work correctly for me...🤞

OEM Green - Red (AF) OEM Green/white - Black (AF) OEM Black/white - Yellow (AF) OEM Blue - Blue (AF) “AF is abbreviation for aftermarket switch” On my 2007 Tacoma, I wired exactly like you did on the second attempt but it didn’t work out for me. I went back and wired as you did in the first attempt but didn’t work too. So, the way how I wired as below and it worked for me, idk how but it worked even though I have the same switch as you had; however, I got the same you issue as you had that was the light turned off when fog lights are on instead of staying on, I assumed this aftermarket switch was internally wired backwards. Anyway, I don’t care, as long as I have fog lights lol. Pin this on top for whoever needs it and thank you for your time making the video.

Sir what if we connect both red wire (Parking & Trigger) in Ignition ???

I used your orientation for wiring but my tail light fuse (located under the inside switches) blows. Mine goes black, white, red, green. Any suggestions? I followed recommendations in one of the earlier comments.

Hi Dan. Great video. I was wondering if you still had the oem connector for the driving lights switch on the Toyota Tacoma. I have a oem switch and driving lights installed and no connection to the switch. Thanks, Rick.

So in fact;the black wire is ground,the yellow wire is positive input(tapping into acc+ for example),and the blue wire is positive out(for light or device),and the red wire is for tapping into the wire that lights up the dash(and that lights up your light on the switch,but not essential for the functionality of the switch itself)?

I have the same dillema these new aftermarket toyota switches are different. They have an internal circuit. Compared to the original switch(mechanical type). New switch Black-ground Yellow-12vdc input Blue- 12vdc output TO relay or load Red- 12vdc input(gauge illumination/parklight) If you bench test the NEW switch and tap the yellow and black wires only and press it on, the indicator light should turn on. The issue might also be(you have to actually check the orig foglight harness), since the orig switch is mechanical type, 2 wires is for the relay coil trigger and ground. And the other 2 wires is for the backlight illumination( 1 wire to back light/gauge(positive) and 1 wire to rheostat(if your car have) if you don't have then its another ground). I have not finished wiring my brother's toyota switch yet, I will have to remove it again and bench test. Update: it was not a Toyota switch it was a generic China switch that has the same design even on other car models(green socket with 4 wires).

Great video. Thanks.

If you look at the wiring diagram for the body control module you see that the blue wire comes from the body ECM and when switched on goes thru the white with black to ground. Power to the fog lights is controlled by pin 7 on the body ECM which has a wire to the fuse block under the hood, thru the fuse, thru the relay to the the fog lights. You are merely controlling ground to the body ecm and the computer directs the power. The fog lights should go off when you turn on high beams and should not work when headlights are not on. the other two control the light inside the switch.

My thought is, as long as the dash light bulb on the switch is Not led than switch the ground wire and the dash light wire. Most likely the dash light and indicator light share a common ground. If so than if the ground wire and dash light power are reversed, the indicator light will get it's ground only when the switch is off. My idea is that it works like a tail/turn light. If you've ever lost ground to a tail light, if you look the turn signal works normal with the lights off. But with the parking lights on, it flashes opposite the other bulb. It does that because it's pulling it's ground through the other filament, not from a direct ground.

Very nice job thx man

How did you wire the LED light bar switch from the the 3 prong red circle button?

My 05 oem switche was illuminated until bulb went out

I tried this took me forever because nothing is clear as far as instructions from anywhere online one I finally got it my fog lights wouldn’t go on at the same time as my headlights. This is ridiculous

My wires out of my truck are Green Green white stripe Dark Grey white stripe Lite Grey white stripe Wires on my switch from the Top are Red Green Yellow Black Pls help yota brothasss thx

you did nothing wrong. Mine did the same as yours when I wired it up. I've tried every possible way and nothing worked how i wanted it to. the best way to get your switch to work how you want it to, is to bypass the factory fog light wiring and buy a led light wiring harness with 2 leads, comes with everything you need ( cheap on ebay )and run new wires from lights to your switch. Plus they will now stay on when you use your bright beams too. I discovered previously on another switch that the top light on switch was too bright and i didn't like it, so on this one I only wanted the bottom light to come on when i turned headlights on, so I could see the button when driving at night. I used 3 of the factory wires and all 4 on switch ( 2 twisted together ) to get it to work this way, the switch worked how i wanted it to. the button is lit so i can see it at night. Next I'll do the foglight on with high beam mod,

What can I do if my car has two red wires and both have power?

Think what you need to do is cut that top wire and wire that into your activated fog wiring. So basicly you will only be usine 3 of the 4 oem wires.

Please, Where can I get the graphic of switch wire you show at 7:47?

no need to replace switch, just replace the orange light on switch you took out, easy fix, it's right there on the side of the switch, all you need is a small flat head screwdriver to remove and replace it. I just did this for my fan control knobs.

Did you ever get ut to work properly?

My switch stays stays on even if my cars turned off

Poooooommmmooonnnnneeee

Mines even worst, I tried installing this switch in my Mitsubishi Eclipse 4g none of the switch lights come on and I have to press two times to turn on my fog lights I should’ve just got the oem one so my advice is do not buy this switch it’s hot garbage

You/We are thinking like 20th century logical western Caucasian’s; My wife, like 21st century emerging eastern nation nerds, and would understand the logic of the illumination sequence. I orient, hold or view a road, navigation, topo, or moving gps map North up; top of the printed map page always up. She/they rotate it toward the direction they believe they’re headed. It works for them. Same with global takes a village early 21st century On/Off power switch symbols - O for off, l for on ( or is it he opposite???) How about assembly instruction in some regional Far East translation of English? Get over it.
