Always on fogs?

2020 Tundra 1794.

I do a lot of night driving in rural, deer infested areas. I'd really like to run my fogs along with my high beams so I don't get jumped by Bambi. I've had a few close calls recently.

I'd be willing to upgrade my fogs for more light as well.

Any cheap and easy way to do this?

and to be clear, I can't recall the last time I drove in significant fog... encounters are almost daily in the early fall!

 

Wouldn't ditch lights be more suited to your needs? Wire those up to a switch and turn them on when needed.

 

I did the old school mod on my 2014..
But it won't work on your truck.

I'm told this works with your truck, but I don't have first-hand knowledge..

I bought one, haven't put it in yet. I believe I got the 'fogster' version.

Thanks for the link. This looks relatively plug n play (my wheelhouse).

Let us know how it works for you/install guide would be killer. Thanks!

 

That looks like just what I need!

 

Fwiw, I spent many years in a similar situation and always used the stick on whistle things from yesteryear with great success. I think the secret is to make sure they don't get clogged up and the mounting position is adequate for function. Thanks for reminding me to get a new set to add to the Ranch Hand Bambi killer.

 

I did it on my 2019 using the factory fog switch on the stalk and a relay. I would assume a 20 is most likely the same wires but i can look on TIS to double check. I can get the wiring diagram and help guide you if you would like. There are two wires that you need to cut at the main body ecu. One supplies a ground signal from the fog light switch into the main body ecu and then the main body ecu outputs ground to the fog light relay to make them turn on.

 

So you just add an additional relay at wherever you're saying to make the "cut"? And is this something that an electrical dummy like me can do?
And that will allow independent action of the fog lights - they can be switched on when headlights are off, DRLs only, and with HiBeams too (I also have a 2019)?

 

Yes exactly. And yes you can turn the fog lights on anytime the ignition is turned on regardless of what other lights are on. The point of the relay is just so the lights will turn off when the ignition is turned off. It will only supply ground to the fog light relay if there is ignition power to the relay. I'm working on putting together pictures of the wiring diagram now. I also confirmed the wiring is the same for 2017-2021

 

I know it looks complicated but essentially all your doing is connecting the red wire to the cut grey wire via a relay. The two connectors are right next to each other right next to the steering wheel. If i can find some time ill try to get a video or pictures of the connectors and wires so it doesn't seem so scary lol.

 

That would be great. I feel like I just drank from the wrong cup in Indiana Jones.

 

In Montana I knew someone with those on his car. I will admit I never heard of him hitting a deer or an antelope, but elk were another story. With these on his car(s) he hit one elk, a year later an elk hit him (car). So maybe they just piss off elk?

 

Or maybe they were plugged up with debris, not mounted properly? Who knows, I only know they worked when I used them over ten years.

 

Sorry, turkey day had me a little held up but i was able to take apart a fresh tundra this morning. Here's the wires that you need to use. After that you will just need a ground at pin 86 and ignition power for the relay at pin 85. These connectors pictured are right behind the knee trim panel to the left of the steering wheel. Hope this helps!

 

I did the $5 fog light mod on my 2017. Search the Mods link. Basically, you put a jumper in the fuse box under the hood and ground it. Super easy. This mod has your fog lights on anytime you use parking lights, regular headlights or high beams. I've had it installed for 4 years and I've had zero issues.

 

Here is a link to the mod:

That's definitely a quick easy way to do it. I just prefer to be able to control the fogs with the factory switch and still see the indicator turn on in the instrument cluster when on.

 

I agree, this works, cheap, easy, age easily done. On my 14 I did this first and ran it like that for a while but then did the "Eddie V's" fog light mod which is similar to the one you're explaining but slightly different.
