Help with Fog Lights!! (I HATE WIRES!)

[Lafiro]

Well congrats.....

I foudnout my horn works. But absolutely NO wire in the harness received power when I press the horn. Yet if I run positive power to the horn it sounds loud and clear....

So something is wrong with the wires between my steering wheel, and the fuse box harness in the engine bar :( (maybe even the relay)

But atleast now I know that warranty will cover that and I don't have to worry about it.

As for your fogs, look at my attachment. Its VERY simple. Engine bay the fogs will have two wires, a red one, and a black, the black I show goes to battery ground. The red goes into the modified red cable that splits into two, and that new red cable as you see goes into those two pin slots in the fuse box of the engine bay.

Inside the car is a different story. As you were told, the relay that came seperate is installed by the brakes. Where all the other relays and fuses are by your feet in the car.

From the entire mess of cables you have, one end which connects to the fog light switch, one end that ahs a relay, and all the other ends that only have 1 wire going to them, go ahead and cut off EVERYTHING except for the end that connects to the fog light switch(and all the cable/slack that can be left with it).

The end goes into the fog light switch, and the red cable goes under the steering column harness.

The black goes to ground.

And your done. Yellow wire goes nowhere, but somehow it receives power when the fog light switch is pressed to be cause not to ground that out. Garm, nor anyone else can explain to me why this happens. Nor why the switch cant light up when the other lights are on, why it only lights up when its pressed, which sucks kindof. Cause I have a cable hanging doing nothing.

PICS!!!!!!!








They're aimed a lil high, but it's raining so I can't adjust them. I'll lower them just a tad bit when it's dry.

I reattached the old relay. Those 3 wires had to go somewhere....

So pretty much attach the long red single wire to ray's oem kit. (2 wires that go into pin 1 and pin 2 in the engine bay fuse box) With the old relay i attached the red wire coming out of it to the battery. It has a fuse along with it. Installed the other relay inside the car where the fuses are at. Install the inside switch via ground and red wire to the yellow d4 wire at pin #3.

Note: I didn't install the yellow wire (coming out of the switch inside the car) as it also didn't allow my fogs to turn on when they were spliced into both the yellow d4 wire or the dimmer wire. So I left the yellow wire from the switch inside the car hanging and taped off.

Now when I press the switch inside the car... the fog lights turn on! and off when I press it again. Now I just gotta mount it... but i'll take pics later tonight!

Only problem is the switch for the fog lights stays on... but I doubt that'll drain my battery.

Those instructions you gave me were good but it doesn't say anything about what to do with the wires once you remove the relay (the relay coming from the wires... not the relay you put inside)... nor does it say to do anything with it. To a complete noob like me ... it will confuse people. It doesn't say to tape it off or connect it anywhere. I'm just relieved I got it to work. Anyone have questions ... please feel free to ask.

The relay you hooked up to the battery is not meant to be used , nor are the wires that where attached to it , you are now running your lights off

Just installed my fog lights I bought on ebay. Had to re-wire them for my pre-wired yaris. I have one wire from both fogs going into the fuse bonnet, while the other grounded to the battery. Inside, I have a relay I borrow from the fuse box, (headlamp relay). One wire from the switch is tapped into the wire from pin 3 of the D4 Connector while the other wire from the switch is tapped into pin 4 of the D4 connector. Third, and last, wire from the switch is grounded. Fog lights work when they are supposed to, (when parking lights are on, fogs work when switch is depressed and light appears on dash).

My problem is that the switch is always illuminated and when depressed to turn on fogs, the switch LED turns off. I know that it probably won't drain my battery, but I dont understand why its backwards. Can the LED be removed from the switch?

I switched the wires that were tapped into the D4 connector but no joy, same problem.

So far, there are three different wire color combinations that I've seen on the aftermarket fog light switches. Thus far all of the switches that I've seen have 5 pin connectors:

#1 - Black, Red, blank, Yellow, Red
#2 - Red, Black, blank, Red, Black
#3 - Black, Yellow, Red, Yellow

The one I received with my kit is #2 above. Here's a picture of the rear side of the PCB with the connector attached (which shows wire order listed above):



Following that ordering of pins and with my switch being #2 and the middle one listed for each pin below, here is the switch wiring that will make the two indicator lights on the switch function correctly (i.e. turn off with the ignition, etc.).


Pin 1 - (black, red, or black) - Green Wire of A/T Illumination (Conn D20 - Pin 2) = +12V
Pin 2 - (red, black, or yellow) - Orange Wire of Headlight Switch Connector (Conn D4 - Pin 4) = Ground
Pin 3 - No wire, No Connection
Pin 4 - (yellow, red or red) - Yellow Wire of Headlight Switch Connector (Conn D4 - Pin 3) = +12V through coil of fog relay
Pin 5 - (red, black, yellow) - Tied to Pin 2 above, within harness

Thanks for the detailed response. To clarify: My switch is of configuration 1. The black wire is ground, because it has a eyelet, so I grounded it near the specified bolt near the clutch. According to your instructions, this black wire, (pin 1) should go to Conn D20 -Pin 2? For manual transmissions, is this Conn just laying near the stick below the console?

Also, according to your instructions, it appears that I have the same configuration minus the ground. I have the red wire tapped into pin 4 of Conn D4 and the yellow wire tapped into Pin 3 - Conn D4. Would you agree that the misplacement of the black wire would cause my problem?

The black wire with the eyelet is only ground if the switch is hooked up to the relay assembly included with the kit. When you wire the switch into the OEM setup (using the OEM wiring and OEM relay) then that wire needs to see illumination power.

D20 is the unused connector in the console on a manual transmission Yaris.
