ADD fog light on 2012 Prius 4

If you're talking about the white one by the speaker, there is no wires to it. It seems to be a dummy plug for the speaker. I disconnected the speaker and plugged it into the dummy plug and it fits.

 

That plug is not for the fogs. The fog lights wires would be in the same connector that the DRLs & turn signals use. There are about 4 empty slots it that connector.

 

hmm, thats not what I was hoping to hear... I should have looked closer at it.. Thanks for all the replies...

 

Get More MPG, you don't need that anyway.
It takes five times longer to get the bumper cover off than it does to run the wires and install the switch.

This looks much harder than it is even for a guy with a bad back, and nerve damage in one shoulder and neck.

 

Yeah but i'm a stickler for OEM stuff. I have been moding cars for a good 20 years and almost all of my cars you would have to really look hard tell if the mods were original or aftermarket....

 

Newbie error

 

Bringing an old thread back to life for a quick question!
I am adding fogs to my 2012 as well! I received the grill today, the fogs are not arriving until Monday
But I was planning on removing the bumper cover this weekend and changing the grill anyway. From all my research it seems like unmounting the old grill and mounting the new one is the most time consuming so I can still get something done this weekend and finish up the install next weekend.

I saw the pictures of the bumper cover and the foglights earlier in this thread- my question is this:
Do you need to mount the foglights in the bumper cover before you install the grill or can you just install the grill like I am planning to do and then add the fogs later?

I understand this may require the bumper cover to come off again to install the fogs and this is not my concern but from the pictures of the bumper cover with the test fitment of the fogs it almost looks like the black grill sandwiches the fogs between the grill and the cover which would mean if I went ahead and installed the grill now I would need to pull it off again to install the fogs later on (not something I want to do).

so: Safe to install grill in advance? or More work later on because I have to remove the grill a second time to mount the fogs?

 

It's easiest to do it all at once. However, since you're willing to pull the bumper cover again, then you can mount the grill this weekend then install the foglights next weekend.

The foglights install from the back of the grill openings, they are not sandwiched between the cover and grill.

If you have installed foglights before, you can probably do it with the bumper cover and grill on, but since this is your first time, you probably need to see what you are doing better.

 

Well I installed the grill no problem and got the bumper back on but now I have run into a problem that I dont know how to fix

The drls wont work! The harness is reconnected and all.... the turns signals work but I cant get the drls on no matter what I try to do: manual switch for them, unplugging and reconnecting harness ect. I dont know what could have gone wrong

 

Now all I need are the fog lights!

 

Did you figure out what the problem was with the DRLs?

 

Yeah I made another post about it but I think it was user error.
When I reconnected the bumper I did what I thought was standard diagnostics to make sure everything worked (everything that may have been affected by taking the bumper off):
>put the distress flashers on
>turn the headlights on
>beep the horn

So to test the DRLs I put the car into running light mode on the headlight control knob =)(= and started the car.
At this point the only thing that came on was the marker lights in the headlight assemblies. I ttoally couldnt get the DRLs on and even went as far as removing the bumper again to examine the harness. Finally I put it all back together and was getting ready to do some real diagnostics with volt testing but it just so happened that my multimeter was dead. As I was leaving to get batteries I saw my DRLs reflecting off the bumper of other cars.

So I did some more tests ansd it appears that when I first get in the car and start it (press brake and press the start button) the DRLs do not come on even of the car is in the =)(= mode (I am usually in Auto which has the same results). The moment I put it into drive or reverse the DRLs come on.

I guess I never noticed that this was how it worked but the results seem consistent so I guess it is normal. I am still suprised that I cannot force them on from initial park position. They WILL stay on if I have been driving and put it into park. It just seems to be something at the point where they initially come on.

 

Yes, my Camry has the parking brake override on the DRLs as well. They come on only if in drive or reverse, and the parking brake is disengaged. But, as have observed, they stay on if you put the car in Park, and engage the parking brake till you turn off the ignition.

 

yeah im such a noob. On the bright side I took that bumper cover off a second time in like 5mins flat

 

Didnt do the wiring yet but mounted without having to take the bumper cover off again. This is the kit from Priuschat shop.

 

Nvm I decided to read and found the answer....

 

Finally done. I wired the +12V for the switch into the cigarette lighter instead of the ecu harness...

Fogs alone


Fogs and DRLs


Fogs and HIDs

 

Glad u got it all figured out

 

They look great. Check the aim on them, if you need to adjust them, there are adjustment wheels in back of the housing.

 

Hey everyone, so I bit the bullet too and added the fog lightsl. I ordered the Yaris lights from eBay, and the grill from the link in a previous post. The picture from the listing on eBay had the correct switch, however I received the wrong (other 2 piece) switch. I contacted the seller and at first he said the switch is random when you order the lights...I called BS and then he said that they are currently out of that switch and will refund me 9.99.

I won't tell you what my first thought to this was, but my second thought was there's no way a stock Prius fog light switch is going to be 9.99. Not only that, I've looked online a bit (limited to searching while at work) and can't seem to find the switch sold separately. Anyone got any ideas? Other than a toggle or whatever switch? I wanna keep it factory looking. Thanks in advance!
