Super solid video! I have a 2015 SR - which doesn’t have factory fogs or intermittent wipers. For anyone curious, this video works for 3rd gen Tundras too. Your instructions worked perfectly, thanks! Also, where did you find wiring diagrams?
You need to connect the pink wire from the Main Body ECU to one side of your Normally Open fog lamp switch wires. You will also need to connect the other side of the switch wire to a chassis ground location. You can just tape off the other side of the pink wire that would normally go to the multifunction switch. When the switch is pushed/locked in, it will ground the circuit and give the BCM the input it needs to energize the coil on the relay. Make sure to double-check your wiring, fuse, and relay.
Hey. I connected red wire coming from fog lights to a relay and grounded the black wire. Connected it to a switch and my fog lights won’t turn on. Do you know why?
Thanks alot C, great video. Would you pls asking for another video where you can explain how to install traction control push button/ VSC button? I have sequoia 2011 2nd gen where isn’t come with that push button. For the Tundra it come by the dealer under the right side of the steering wheel. Really i would be thankful🙏🏼🙏🏼
It’s not a fuse the wire was brittle and broke in half. I have to depin and repin with a new wire and solder back together. Looks like a 22 gauge but I’m not sure.
I’m trying to do this myself. I have don’t have the blue and yellow wire for the switch. I have an aftermarket wire set up. Two red wires, one yellow, one black..Anyway to tell which one I need to connect to the pink wire? Ground?
I had to rewatch my video to help find an answer for you. You'll need an ohm meter to check continuity of your aftermarket switch to find the normally open contacts. You'll then connect one wire to the pink wire going to the BCM and connect the other wire to ground.
In first gen Tundra, the wiring for the fog lights are already pre-wired. Just install a new fog lights, new relay, new fuse (if it does not have one), and the new switch. Is this not true for the 2nd gen Tundras?
What wire would I tap into for an aftermarket light kit that has a red wire to power on the switch? I’m not using the factory wires but the wires that came in the kit. I got the fog lights to work but I cannot find a wire to tap into that only powers the switch on when I turn the ignition switch on. All the wires I tried kept the switch kit on all the time whether the ignition switch was on or not? I thought I tried the pink wire but maybe I didn’t.
I did some more digging and it looks like Tundra doesn't have a fog light on indicator in the instrument cluster like I originally thought. Maybe they added the light in the later years.
@C Muss The pink wire im not sure where it goes to. But if anyone is wondering the same thing. I grounded the light blue wire from this tutorial at 3:26. ruclips.net/video/OQiFLtb-mnU/видео.html Bam, when I click on my driving light my foglights come on.
Every kit is different. It's been a few years, but I believe I would have to connect one of non-contact switch wires to the tail lamp green wire and the other to ground. That way the button will illuminate when the parking lights are on.
@@ballz50401 got the button to light up (mine is Amber so I wanted it) by connecting one wire to ground and one to the parking light wire, which is the light blue wire in the top harness above the harness with the pink wire shown in your video. And fog light switch wires connected to said pink wire and ground
Yeah. You could get away with doing that too. The pink wire going to the multifunction switch is probably in an empty terminal so it shouldn't short anything out. I'm not a fan of wire tap connections. I prefer soldering for a professional installation.
Your instructions worked perfect. It took me awhile to figure out which pink wire to tap into but eventually got and everything worked great. Thanks!
Perfect!
Thank you!!! I've been looking everywhere for an indepth explanation your the man!!!
Man your video was SPOT ON !!!! Just installed led pods for fog lights in my new custom bumper and it worked perfect !!!!
I'm glad my instructions worked out for you. 👍🏻
Just followed these instruction on a 2007 Tundra worked. Followed this video was a snap, thank you

Also, where did you find wiring diagrams?
My local library has free Online Chilton Library Edition access. Lots of good repair info.
I wish there was a video of you showing them turning on and off with the button.
What do you do with the other end of the pink wire ?
I followed the steps but lights are not coming on
You need to connect the pink wire from the Main Body ECU to one side of your Normally Open fog lamp switch wires.

@@Surge1109 Are you using the factory wiring or an aftermarket wiring harness?
What did that pink wire do before it is clipped and re wired? It looks like in the diagram table it links to something.
Instructions not clear my truck caught on fire

What gauge is that pink wire from J3 pin 28? I don’t have any taillights once I clipped it. Help?
I'm not sure, maybe 18 gauge. I'd try and check your fuses.
It’s not a fuse the wire was brittle and broke in half. I have to depin and repin with a new wire and solder back together. Looks like a 22 gauge but I’m not sure.
What if I want to set it up so that they can work even with the headlights off?

Probably but the "factory" switch in the 07 is on the turn signal/head light switch... which is a pair in the ass to deal with.
What wire would I tap into for an aftermarket light kit that has a red wire to power on the switch? I’m not using the factory wires but the wires that came in the kit. I got the fog lights to work but I cannot find a wire to tap into that only powers the switch on when I turn the ignition switch on. All the wires I tried kept the switch kit on all the time whether the ignition switch was on or not? I thought I tried the pink wire but maybe I didn’t.
I would tap into the cigarette lighter. There's a green wire that's fed off of a 15A fuse. It's switched on in ACC mode.
@@ballz50401 thanks I will try that when the weather gets better
The wiring is there for the lights but I don’t have to pink wire coming out of my j3 connector…
What year and trim is your Tundra?
Here are the wiring diagrams for my '08 DC.

Is there any method that has the dash console indicator light toggle?
I did some more digging and it looks like Tundra doesn't have a fog light on indicator in the instrument cluster like I originally thought. Maybe they added the light in the later years.
You do not need to cut anything in the harness just for your information😀
How?
So if i ground that pink wire, my foglights will be on whenever my driving light is on?
That sounds about right. You'll need to add the relay in the factory location if it wasn't factory equipped.
@C Muss The pink wire im not sure where it goes to. But if anyone is wondering the same thing. I grounded the light blue wire from this tutorial at 3:26.

Bam, when I click on my driving light my foglights come on.
So what would be different if you wanted to do this but also have the button illuminate?
Every kit is different. It's been a few years, but I believe I would have to connect one of non-contact switch wires to the tail lamp green wire and the other to ground. That way the button will illuminate when the parking lights are on.
Appreciate the response! Going to try this tonight
It all worked your the man thank you
@@keeganrawlins5821 Nice work!
@@ballz50401 got the button to light up (mine is Amber so I wanted it) by connecting one wire to ground and one to the parking light wire, which is the light blue wire in the top harness above the harness with the pink wire shown in your video.

Can i Tap on the pink wire instead of cutting it? Wish me luck 🍀
Yeah. You could get away with doing that too. The pink wire going to the multifunction switch is probably in an empty terminal so it shouldn't short anything out. I'm not a fan of wire tap connections. I prefer soldering for a professional installation.
Would a t tap work vs cutting the wire?
You could get it done with a T-tap, but they're not my favorite. I'd prefer butt spice connectors over T-tap, but that involves cutting the wire.
@@ballz50401 i tried the t tap... didnt work.... really didnt want to cut any wires but cant hurt i guess if that pink wire is only for the fog lights
Is it the same wiring with 2011?
Yes, after reviewing the schematics from a 2011, I would say they are the same as the 2008.
