DIY Fog Lights 2004 to 2007 Toyota Highlander 

Amazing video brother did this with my 04 Highlander exactly what needed

Im about to run fog lights on my 2004 Toyota Highlander, this video was super helpful! Thanks, liked and subscribed 👍🏼

About to do this on my 04' Highlander, was grateful to find the wire harness already in place, and the switch right next to the one for the headlights. Thanks for the video!!!

This video was a life saver. I had to chuckle that in 2021 we are both doing the same thing. Thanks for the content.

Great video. I want to do this, and this video was absolutely perfect! Thank you for sharing it.

Love what your doing!!!

Thank you so much for this video I'm going to do this I just got a 2003 Highlander and I put aftermarket fog lights and other lights on all of my cars is where I drive there's always construction and sometimes they drop stuff in the middle of the road you have to avoid and I need to see that and sometimes the edge of the road at their concrete barriers are covering the line and so then all of a sudden you have a barrier in the way and I really need to see that as well so I'm going to add these fog lights as soon as I can thank you so much

Thank you ! My Haynes manual had the wrong color wire in the diagram and I was getting nowhere.

Is there any link you could provide for that relay? I want to make sure I’m getting the correct one. Also that’s some awesome work! I was afraid this was going to be more involved

I have a 02 V6 awd Highlander and on the bumper the fog light mounting looks very different

Thank you so much for this DIY video. Do I need to disconnect the negative battery terminal before performing the activation/installation?

I'm more interested in where the stock relay for the fog lamps is on my 04 highlander are, I'm trying to find a way to get them to work independently, but I don't think this car actually has one.

So if you add the fog lights and plug them in to the empty harnesses they won’t come on when you turn on the low beams? You still have to add the relay?

I'm not a sparky so I have no idea how to do any of the middle work between finding the junction and having the light switch wired. I tried putting my multimeter into the junction and then grounding it and nothing happened. Then I saw you wired it to a switch Do you just run a separate wire from the violet wire junction to your switch? And then connect a ground wire to the switch as well?

If I put the relay and ground the violet wire without a switch if I turn low beam will the fog light turn on itself without a switch ?

Can I get another link for the relay? The one you provided doesn’t seem to work

Do you have any videos on wiring the switch?

Thanks for the helpful video. I am considering adding fog lights to my 06 Highlander. I have a question. There are lighted switches that fit in the blanks on the Highlander - where you placed your toggle switch. The lighted switches on Amazon include a four wire harness. From my understanding: one wire brings in current from the relay, the second wire takes the switched current to an accessory you would be powering (in this case it would not be needed), the third wire is the current source for the for the bulb in the switch itself and can be wired to the ACC power source to light up like other dash lights, the 4th wire goes to ground. My question is, could I use that type of switch in this scenario in place of a 2 wire toggle switch? I would use the first wire connected to the violet wire you mention. The second wire (switched power) I would cap. Third and fourth wires I would splice together and connect to ground so that the light on switch illuminates when switch is powered on. Sorry if this is too much or outa left field. Give it a moment of your time and let me know if you think I am on to something. Maybe you might upgrade to a lighted switch that fits in that empty slot as well. Thanks

Unsure how to ground the violet wire anyt tips?

About to run this now. I went a slightly different way and switched out the turn signal/headlight arm for Toyota’s arm that has the fog light switch. Do I still need to ground the violet wire somehow? I’m getting the relay click when I activate the fog lights but the bulb doesn’t come on.

How exactly did you wire that switch up, like the power wire from the switch to the violet wire, and the ground wire from the switch to a ground point?

hi, it was helpful, i like to know how to disable drl toyota highlander 2006, thanks

I’m just curious on how you wired the switch and grounded it

How do you actually connect the switch? The wiring process for it?

2003 has the harness too?

Shocker. So I bought the turn signal stock with the fog switch, I checked the switch with the multimeter, the turn signal harness has wires for the fog pins... But, the known good relay doesn't click when I switch on fogs on the stock. The fuse is good too... Sadly I hadn't found your video when I was preparing for my installation. Installed the lights with the prewired harness, checked the fuse, installed the relay by moving over the tail light relay, installed the new turn signal stock with the swith... Nothing. Doesn't work. I hope the ECU isn't controlling it. Will check that wire coming into the fuse box, grounding it should make the relay actuate in theory...

Helpful but would have been more helpful to actually install the light and switch instead of just pointing.
