Electrical Advice for New Switches
Afternoon All.
Hoping someone could help with some new switches I'm currently putting in as part of my new centre console I'm doing. I posted a topic a while ago about wiring in a hazard warning switch (can see here viewtopic.php?t=79843) after removing the stereo, I've since bought a new switch from amazon (https://www.amazon.co.uk/Mintice-Vehicl ... 421&sr=8-1) and I've managed to wire it in so the hazards work but having trouble with the live wire to get the light to work.
I've had a look through the electrical manuals and didn't know if this L/R wire in the radio connection might be what I need ?
Here it is currently
If I connect the red wire of the switch to the hazard orange wire switch the light does work however its on all the time without the ignition on and turns off when pressed. Don't know if its a non permanent live wire that I require for this and not seen where that wire would be.
Any thoughts ?

hi, the two wires you have cut from that plug in the picture, does that go to the back of the original switch? without the correct wiring diagram i cant be 100% but based on what i can see there should be at least one more wire for the hazards light switch, maybe two, im just gonna have a look to see if i can see a wiring diagram and will work it out.
Tho i will say that the black cable from the new switch does not connect to the output of the switch as that will be live when on but will be high resistance ground when switch is off, this is why the light turns on normally but off when the switch is activated
Ok got that bit wrong, B/R is ground, orange goes back to the Flasher Control Module, will have a look at mine in the morning as i would have thought that the light will have separate wires to turn it on and off with flasher, unless you just want the light on when the switch is on then the red just needs live and black to orange so it is grounded when on.

innerlurken, yes I've wired into the back of the original, the orange from the flashing module is connected to the green of the switch and the blue and black are connect into the B/R for ground. I assumed the black negative for the light would be ok to go into the same ground. Was hoping there be a live I could use in among these existing connections.

so i had a look at my spare radio, the hazard button does indeed have 4 wires, the issue is tracing the PCB, one of the PCB traces down to connector but does so via resistors and looks to be power but i cant be certain of that, the other traces back the left connector going into the radio unit, have not been able to trace it after that tho, i will keep looking for you as it has peaked my interest as to how mazda has designed this

Would the L/R wire that I've highlighted in the diagram provide the live needed for the light ? Which I think is the radio connection in that 1st photo.

The L/R wire (connector pin 1J) you've identified is connected to the air intake actuator, so can't see that will work?
If I've understood correctly, that you want to illuminate the lamp inside the hazard switch you are installing, when the hazards are on?
Not sure it helps, but P/B (conn pin 2C) will give you a switched live feed, but that means the switch lamp will be illuminated with the IGN on. I'm guessing that's not what you (ideally) need, but the best feed I can see from that diagram.

Is there not a wiring diagram with the switch that shows where to connect the light power wire? If you want it to be lit when the lights are turned or or to only flash when the hazards flash. Or is it capable of both?

Sorry I meant to highlight the L/R on 2A
Yes that is what I'm trying to achieve and by the sounds of it that P/B should work, I will give that a try.
Just to check I'm reading this correctly too. On that diagram, 1K goes to the rear windscreen defrost ? I have a switch for that too that is the same as this one.

Yes on that amazon link there is a diagram for it.

Done it !!!
Used the purple black wire from the hazard connection and the light works only when ignition is on.
Will I be ok to wire multiple things to this purple black wire or does running too much through it run the risk of blowing a fuse ?
Sorry my car electrics knowledge isn't great.

You need the Hazard lights to work when the ignition is Off or On, though it's okay for the light on the switch to only illuminate when the ignition is On - is that how you have it now?
If it's just the light on the switch that you've added to that circuit then it should be okay.

When the hazards are switched on does the light flash irrespective of ignition on or off?

The light is only on when the ignition is on, it stays on whether the switch is on or off. It doesn't light at all with the ignition off. Think that makes sense.

Hm! as Dave has said the switch needs to turn on the hazard lights whether the ignition is on or off and that means that the light in the switch should flash in unison with the indicators.

Sorry don't know if I explained that correctly. The hazard switch works with the ignition off and on. The light on the switch only works with the ignition on.

I think that's the best you are going to get, without laying in an extra wire.
It would be nice to have the lamp in the switch flash in unison with the hazards, but that output is the far side of the flasher unit, so a wire would need to be fed back from that output, back to the dash console to feed the switch lamp. I'm not even sure where the flash module is located and how easy it would be to tap into the output.
Or, I'm sure you could get a little 12 volt solid state flasher module on fleabay that you could locate locally with the switch, triggered from the switch output and to feed the lamp. You'd have to think carefully about the wiring though, if you wanted the lamp to be "on" with the ignition, so it could be seen at night, then flash when operated.

Think how its setup now is as good as its going to get without digging deep into the wiring which don't have the desire to do, hopefully if I can get a good run at it will have this finished over the weekend.

I've put in a switch for the rear screen defog too, to double check looking at the 1st diagram its the GY wire in connector G1-01 which I need, I presume this is the connector going into the back of the stereo shown here and GY wire will be the green / yellow wire bent out ?
This is my centre console to date btw left space to put dials in at some point and got a windscreen fan to go on the top too.
