Fog Light Install Question - Should Be a Piece of Cake for YarisWorld Veterans

[Tomatogrower]

Hey Ya'll,

I recently bought an Ebay Foglight Kit, and the installation was going alright until I encountered a wiring issue. After searching the realms of the internet, I only found one person with the same problem, but for a Toyota Sienna; I couldn't find a solution which I understood from that:

http://www.toyotanation.com/forum/275-3rd-generation-2011/380760-question-those-you-ebay-fog-lamps.html

From the picture in the link above, I don't know where the brown clip and white clip connections go. I am absolutely dumbfounded regarding those two wires... Any help would be greatly appreciated!

I have a 2009 Yaris Hatchback (Base)

Did you get any documentation with the kit?

Although these kits are labeled as being for the Yaris, they really are not by any means designed for them, so the wire colors mean nothing unless there is some documentation on the purpose of the wires. I have seen a few different variations of these kits with different color wires.

Also, these cheap kits are notorious for relay failures that result in melting of the relay housing and connector. I highly recommend rewiring the kit to use the OEM fog light wiring and relay, as the Micro Image kit does. The document below explains the process:

Unfortunately it didn't come with any sort of documentation regarding the wire colors. I feel confident that one of the wires is used to power the fog lights, since I haven't found a means to power them yet. I searched through the web on the kit model number, and nothing came up as far as instructions or wiring diagrams were concerned.

Thanks for the MicroImage document! I've seen it many times before, but if I can't figure this wiring thing out, I may just end up going with the OEM wiring and relay option.

I found the same setup, but the installation is for a Honda.

What do you think?

[Tomatogrower]

So from the previous link, it appears that the red wire (white clip) gets spliced in with the parking light wire, and the white wire (brown clip) somehow needs to be routed to the battery...

I did find another Honda wiring example, though, and they have a brown female clip already built into the Honda...does the Yaris have something like this? (Second to last picture)

That probably is the same. The company that makes them probably uses the same generic harness for all cars, and just changes the lights and trim pieces (which would also explain why the switches don't seem to fit any vehicle correctly).

The Yaris does not have a mysterious hanging connector for that plug like that Honda happened to.

Oh ok, thank you! What would your suggestion be to best route the white wire (brown clip) to the battery? Is there a wire already under the dash which I could tap or splice into? Thanks!

Look in the DIY section of the forum for my Remote Starter DIY for info on where to grab constant or ignition switched power right under the dash.

Excellent, thank you very much! You've been a big help :thumbup: I'll let you know how it turns out!

Sorry, I am a little new to this...where can I find the parking light wire under the dash? Thanks!

I apologize, I just found it:

Pin 29, correct? (Green wire)

Actually this thread is what I was pointing you to:

My documentation shows pictures of the locations.


If you are thinking of having them come on with your parking lights, then you will want to modify the harness per the Micro Image DIY. The way that the included harness is designed, you would connect the kit to ground and battery power (or to have it ignition switched you would use an extra relay connected to the ignition switched power wire per my DIY and would switch the battery power using that second relay).

Thank you! The way I wired it this afternoon was:
-I connected the foglight power wire (white with brown clip) to the constant 12V source
-I connected the switch illumination wire (red with white clip) to the parking lights.

This configuration worked fine temporarily; the switch illuminated when the parking lights were on and the fog lights turned on when the switch was activated.

However, when I put the plastic casings back into place, the parking lights had issues. They will not turn on, which in turn doesn't illuminate/power the switch, so the fog lights won't activate.

Any thoughts? Does grounding at different grounding points affect anything? I checked the fuse, and it was still good. It seems like there may be an issue with the grounding or my tap splice with the parking lights...

Thanks, you've been a big help! I greatly appreciate your patience with this!

If everything worked fine before you put the bezel and lights back in,
then most likely you accidentally pulled or pinched a wire or connection somewhere.
You'll have to retrace your wires. Ground should be a solid ground - to the frame/body of the car would be ideal.

Check the TAIL fuse in the fuse panel under the bottom of the dash. I have a feeling that the red wire was actually the power wire, so you were pulling the power for the fogs from it.

Hm...I didn't think about the pinched wires...I will check! I attached the ground to the ground location just under the steering wheel. I will see if I can attach it to the frame. I find it odd that it would be from a pinched wire though, considering the parking lights don't work; any wire I can see getting pinched would be for fog light wiring.

I checked the Tail fuse last night, and it was ok. I was hoping that was the issue lol, but unfortunately not.

I'm sure the red wire was to power the illumination switch; I was testing the connection throughout the installation, and when I wired the red wire to the parking lights prior to wiring the white wire with the 12v connection, the switch would illuminate without powering the fog lights. So that seemed as a check that it was wired to the correct points.

I would double check the TAIL fuse, as only that and the 120A ALT fuse are in circuit with the tails. Since they worked for a bit and then went out, the fuse may have opened less catastrophically than if it blew due to a short.

The only other thing that may have gotten damaged is the T-LP relay, but that it integrated into the internals of the body ECU, so to replace it you would have to replace the entire under dash fuse panel assembly.

I will check again, however, I have one of those fuse checkers with the illumination lights; the light on the fuse checker would turn on if the fuse is working ok, and it did that. Hopefully it isn't the T-LP relay; that would suck

Also, if you haven't done so already, disconnect that red wire from the OEM wiring to make sure that it is not just a case where something failed within the switch, preventing the T-LP relay from activating.

[Tomatogrower]

Sorry for the uber delay; I moved across the country for a new job and haven't been able to really work on my Yaris since.

I had another set of eyes look at it, and the relay that came with the kit failed. Lesson learned on my end...lol... I guess I must have been looking at the wrong fuse or something before because the Tail fuse did blow out.

I already have an e-bay type kit and re-wiring the OEM style might not be the best option for me. Other than the cheapo relay, my kit looks OK.

Would it make sense to change the relay into smth more reliable? Are there quality aftermarket relay brands?

A bunch of stuff is available around// like this for example.. says OE grade

That relay would be fine. Pretty much any relay would be better than the cheapo ones included with those kits.
