Fog lights are not working. I have no power to the violet/white tracer wire to multi-function switch. Where would this wires power source connection be? [If I power up green wire/pink tracer; fog lights work] This is a Canadian vehicle. Thanks for your help; Leonard

Howdy anonymous,

Beyond the always FIRST STEP of blaming the "FLASHER"....
(see rockauto example $ below)

There immediately follows moving on out to the light bulbs and checking they (EACH & EVERY) work...

Then & only then do you start "BACK-TRACING"

I always recommend getting REAL FACTORY support documents but luckily BBB Industries has FREE documents for popular USA models: and TECHNICAL SERVICE BULLETINS...
(foreign & domestic... (registration required... real documents))

Go to the wiring SCHEMATIC... You will find REFERENCES to both BATTERY & GROUND...

It would be really helpful to know... WORKING STATUS?

Tail lights
Brake lights
Left signal
Right signal...

If Tail lights and Brake lights work... you can
pretty much forget about BACK-TRACING altogether...

Start with your FLASHER power source and move
immediately into the "multi-contact flasher switch

one wire will for high beam
one wire will be for low beam
the last wire will be ground wire
as fog light have only one beam you can use the low beam wire and parallel wire it to the fog lights
that way you have the head lights still and the fog lights as accessories correctly wired according to regulations
how to do it simply-- find the low beam power wire ( light switch on low beam and power at the light bulb check ed with a multi meter set on volts
solder , piggy back, or double plug in a connection into that wire and run one wire to the left fog light and one to the right fog light connect each fog light to an individual ground wire and connect those wires back to the ground wire for the main lights
Now having done that simple addition to the lighting system another problem has come up
The wiring will now be too light to carry fog light current and or the light switch will burn out
To over come this problem, the circuit needs a relay
fit a relay on the bike and now run the low beam wire to a terminal of the relay
run the other terminal wire to ground
this enables the relay to operate when the low beam is switched on but at this will not switch on the lights yet
now you have to run a heavy gauge wire (fused at the battery) to one of the power terminals of the relay and from the other power terminal to the connection for the fog and low beam lights
Now it all works switch on the high beam and no for lights
change to low beam and the fog lights come on as well
All nice and legal
Of course if you don't care about being legal just buy a 30 amp toggle switch and run a fused wire directly to the switch from the battery to the lights and then to ground from the lights
You will know that the generator / alternator for the bike will not be able to run the fog lights with or without the main lights so what will you have achieved

Perhaps you need to start with fog light problem I am guessing we do not know for sure the switch was the cause, if you can remove them from the equation. When checking for shorts make sure you check light bulbs to,
Next, since the multi function switch was the next step in your problem solving, I suggest you remove the new switch check out all wires to the connector, be especially careful to make sure none of wires have pulled out or partially pulled out of the connector. Let me know when you finish this then we can move on to continuity testing.
My best guess is the connector as it is common to both your fog light and multi-function switch,
Above all don't let it get to you, these problems can be frustrating but they also can be interesting and fun especially with the right assistant

check high beam low beam switch

One wire provides power for both high- and low-beams from the light switch to the multifunction switch (on the steering column), and it is a light green wire. From the multifunction switch to the low beam lamps is a violet wire with white tracer, and to the high beams is a red wire with an orange tracer.

jonj1138: BINGO! I believe you have probably hit on the correct source of the problem. Who ever installed the radio, probably looked for the wire which supplied power when the lights were on which should be the red wire with the blue tracer. They have somehow tied the unswitched circuit into the lighting circuit. They may have even picked off of the the cigarette lighter.Then they tied it into an Unswitched power source, not thinking of the feedback.
Unswitched power sources: a red with a white tracer and a red with a black tracer. I believe I have the correct colors It's been years since I have worked in a ZX ans I don't have a SCHEMATIC handy. I am doing this from memory. There may be two wire connected to the Unswitched power supply. From your stereo, you will have a Yellow wire. This is the Memory wire. Leave it hooked up to the Unswitched power supply. The other wire needs to be disconnected and if it was hooked up to light the for the radio, hook it up to the red with blue tracer. That will be the switched circuit for the lighting.

I hope that this will solve your problem. Good Luck!

on a 2000 jeep grand cherokee the violet wire with a black tracer is the power for the backup lamp ...the black is ground

This should get you going:

The 2 Blue with a Yellow trace are the POWER wires

The Grey wire is the ACC

The Pink wire is Frontt Left +

The Violet wire is Frontt left -

The Green wire is Front Right +

The Blue wire is Front Right -

The Black wire is Rear Left +

The Yellow wire is Rear Left -

The Red wire is Rear Right +

The White wire is the Rear Right -

The Brown Wire is the GROUND

The Black with a Red tracer goes to the auto antenna

The Pink with a Blue Tracer goes to an aux amp, if you have one.
