Need Help Wiring Fog Lights

[MadMax]

I got a set of the nice Taiwanese fog lights from Kargoboy and I got them installed into the nose and the wire running into the cabin; but I am having problems figuring out the interior wiring.

The set included a harness where one end plugs directly into the button that goes underneath the parking brake. No problem there. The other end has a large plug that goes into the relay, and the wire that comes through the firewall also goes into it…easy enough.

Now, I have three wires left. One has a loop so I naturally assume it is the ground. Another is purple and has a small female end to it. I think it goes into the fusebox somewhere. The last is pink and stripped at the end, no connector.

Now, I want to be able to run these without the lights on; but I want them to be tied to the ignition so they go out when the car is shut off. If anyone can help me in determining how to connect these remaining wires to give me that set-up I would be very grateful! The inside of my Yaris is torn up until I get this done, and I want to get it back together as soon as possible!

Cheers! M2

I believe one is constant power and one is (as you want) ignition power. I used running light power, that way you can't accidentally leave them on. You can test which wire is which. I think if you get them backward the switch just doesn't light up correctly. Sorry I can't be certain, I sold the Yaris awhile back and can't just "go out and look". Good luck

[MadMax]

Thanks Peter, I guess I'm just gonna have to experiment to figure out what the purple and pink wires are.

Another question, will the fogs get power from the fuse box or should there be a power line running to the battery? I ask because with the two harnesses I got, there is nothing that connects to the battery. The one in front has two connections to the back of the fogs, a ground wire, and a wire that runs into the cabin and connects to the second harness. That one has a connction that goes to the switch, one that goes to the relay, and the three remaining wires that I asked about, one of which I believe is the ground wire and the other two as you mentioned are constant power and the ignition. I am just curious as to how I am going to work this out...I hope I don't have to pull the nose off of my Yaris again! That was a pain...

Cheers! M2

The purple wire is your constant power, the light pink wire with no connector is your switched power, and dark pink wire that went through the firewall plugs into the foglight relay.


You can follow the pictures below. That is how I have mine setup. Purple wire goes in and locks in place in that connector below(follow the red arrow if you can see it). Light pink wire you will have to modify the harness to get to that connector near the shifter. Open up the wire harness near the green/white wires, find light pink wire & cut it and tap it into the green/white wires near the shifter. That green/white wire powers on the lights in the shifter for automatics, for manuals its just tucked away unused. Connecting the switched wire onto there allows you turn on the foglights with the parking lights and goes off when you turn off your headlights

Thanks, that's the info I was looking for. But yet again I have a question, can I just wire them into the fuse box as such...

Obviously substituting the appropriate wires?

Cheers! M2

[MadMax]

if you follow the esuse method you conect it to the fuse box in the engine bay without having to go through the firewall

Thanks, but I've already run it through the firewall...and I think the harnesses I got where meant to run off of the inside fuse box.

Cheers! M2

[FunctionSpec]

You can? You just need the correct connectors. Only probably with that setup is that it turns on when you turn the key to ACC so you have to remember to manually turn on and off the foglights everytime. If you connect to a wire that switches on when the parking lights are on, you are able to turn the foglights on/off with the parking lights and since you'll probably turn on parking lights at night anyways, it just seems more convenient.

You can also run it through the fuse box without going through the firewall but limits the ability to turn them on whenever you like. You can only turn on the foglights if the headlights are on only. Nice feature about that route is that the foglight indicator lights up on the dash when you turn on the foglights

[MadMax]

OK, hopefully this will be the last question!

Based on the two wires going into the inside fuse box (below), what connectors do I need for where the red and white wires go?

http://i78.photobucket.com/albums/j111/jthomas43613/P1000397.jpg

The white one seems like a simple female connector (albeit a little smaller that usual) but I am not quite sure about the top one.

Cheers! M2

[FunctionSpec]

You need the connector from the purple wire to connect the switched wire(light pink) like the red wire in the picture. Then you need a connector like the dark pink wire that you plugged into the relay to plug into the connection that the white wire is connected to.

[MadMax]

This is driving me nuts, I swapped the connector from the purple wire to the light pink one; and it does not fit in the place shown above! I have the purple (white above) wire hooked up, but there is only one way to get the connector in that hole and it is very loose. I tried Pep Boys looking for another connector, and all they have are smaller ones. Does anyone know where I can get the right-sized connector?

And, just to recap; these are the only two connections to the car, right (except for the two grounds)? I have the harness hooked up to the lights, then grounded and through the firewall, Inside that wire connects to the relay, and there is a wire that runs to the switch in the center console. There are three extra wires left to connect, the ground (done) and the purple and light pink wire. These go in the two slots in the fuse box shown above (purple --> white and pink --> red).

No ideas? If I can't figure this out, I may have to take it to my local shop...

You can grab switched ACC power from the steering column and then you won't need the proper pin for that connector. You can just use a wire splice. The white wire on the keyswitch connector is ACC:

Thanks for the suggestion, but I was hoping to be able to wire it as (I believe) it was intended. Plus, I am concerned over cutting wires (I'll admit it, I'm a chickenshit when it comes to my new car).

I'm curious, can I at least test the connection by sticking a bare wire into the location in the fuse box?

Cheers! M2

[FunctionSpec]

I would just put everything back the way it was and follow my original directions. I have installed 3 of kargoboys kits that way with no problems. Stop following that other picture, its for a different kit which requires different connections.

You can hold it against the terminal to do a quick test.

You actually don't have to cut the wire to tap into the column circuit - You can use one of the tap splice connectors like this (available a most autoparts stores):

Will do, but that still doesn't solve my problem of the loose connector for the purple wire that goes into the fuse box.

And would the tap splice connectors CTScott posted work with tapping into the gree/white wires near the shifter?

Cheers! M2

[FunctionSpec]

Hmm, how is the connection "loose". Does it jiggle around in there or does the connector just slide out? Probably putting it in the wrong way or probably not pushing it in all the way. It should click into place. Disconnect that harness and then try to put in the connector. It should slide right in and click into place.

You can use those splice connectors or the t-tap splice connectors. Just remember to get the right gauge.

[ToddR]

Just remember to get the right gauge.

Do you know what gauge the Yaris foglight wiring is? I'm planning on adding fog lights myself. I bought these (http://www.mouser.com/Search/ProductDetail.aspx?R=951K_(BULK)virtualkey51730000 virtualkey517-951K) and want to make sure they are right before I get started.

You might want to get a couple of 14-16 gauge ones as well. There are a variety of different gauges used. The important thing is to make sure that you match the tap splice to the gauge of the wire on the car (never use a tap splice that is smaller than the car's wire or you will damage the wire). Or, use a T-splice like in FunctionSpec's pic. These allow you to connect two wires with different gauges.

[MadMax]

FunctionSpec

It only goes in one way, if I turn it any of the three other ways it doesn't even go in. It just slides in and out quite easily, no 'click' in place.

Cheers! M2

OK, got the ACC power (purple wire) working, although I may have to tap it into the white wire CTScott recommended as it still doesn't seem to snap in tightly. But the light on the switch does work when I depress it.

But now I still have to do the pink wire to the green/white wire near the shifter. I pulled the console again and noticed there are two pink wires on the connector to the fog light switch...

http://i28.photobucket.com/albums/c209/M2Repsol/IMG_2246.jpg

I just want to make sure I want the one on the left, next to the striped wire.

And, of course, this is where I tap it in...

http://i28.photobucket.com/albums/c209/M2Repsol/IMG_2247.jpg

And, just to put the cherry on top, I just noticed that the driver's side fog light lense is cracked. Must've taken a rock already. Freaking heck, I just can't win with these things!

Cheers! M2

[FunctionSpec]

Purple wire is suppose to be constant power and not ACC(switched power) but you can set it up the way you are right now. The way you are setting it up right now allows the foglights to only turn on if you have key set to "ACC" and have parking lights on.

If you put the purple wire to a constant power, you can turn on and off the foglights with just the parking lights without having the key in the ignition. Since the headlights & parking lights can be turned on/off without the key in the ignition, wiring the purple wire to a constant power makes the function of turning the fogs on/off more linear with everything else.

The light pink wire splits into a "Y" so thats why there is 2 pink wires right at the harness. If you go further down the harness, there is only one pink wire and you connect that one pink wire to the green wire on the harness with the green/white wires.

Also since its connected to the illumination circuit, if you dim your interior lights too low, it will shut off the fog lights.

[MadMax]

Gotacha, I am going with the instructions you sent me, so the purple wire is tapped into the fuse box where you said it needed to go. I will strip down the harness to find where the two pink wires converge and then cut and tap that into the green wire as shown. That is the right wiring show in the second picture, right? I have an auto, and I thought on manuals it doesn't connect to anything as it does on my car.

Thanks! M2

[MadMax]

FINALLY!

I am not sure how I got it, but they work! I got the tap and connected the pink wire to the green wire by the shifter; and for the purple wire I put a female end on it and plugged it into the two open male ends in the fuse box.

The fog lights come on when the button is depressed and the lights are on. Turn the lights off, and they go off. Just what I wanted. I also checked the dimmer switch, and it has no impact on the fog lights.

Now, I still have a cracked lenses on the driver's side; but I will contend to that when I get a chance. For now the lights work and look great.

And now I can also do my one-minute vid for the other thread. I have to find a nice place to film it, I would love to do so in front of the Alamo but traffic is blocked off from getting there. I have a few ideas and hope to get my vid up soon!

Again, thanks for all the help; especially FunctionSpec who has been more than patient in guiding me through this!
