I have a Mk 2 JDM 1800cc 1999 with fog lights in the mouth but i also have now fitted an after market spot lamp set that are fitted into the front nose cone/bumper very simular to that fitted to the Mk 2.5. All the wiring & relays are in place and ready to go,But…
Now the problem i have is, i would like to keep both set’s on the car and the Mk 2’s are very limited to space inside for an extra switch to fit plus i still have the jdm double din head unit in place so no room there,so i have won on that there e-bay a 2.5 double english fog lamp switch>>>great…now thats the problem, the bloody switch,one side clicks on/clicks off,the other side just press’s in and springs straight back??? HOW DO YOU WIRE IT IN???,WHAT ELSE DO I NEED???this has me beat, i need your help, PLEASE, PLEASE, PLEASE.
Someone out there must of come across one of these switches and mastered it.“HELP ME”
You sound a bit desperate there Wayne, just so you don’t feel ignored and that no one cares, I have no idea what you are talking about. Switches are a very hi tech piece of kit, that I as a …
Ok that’s taken the PPP Never seen one of the switches you describe mate, perhaps a pic or two and a look at the back. Have you metered the switch to see what connects to what, when you press the various bits?
Thanks for replying,i’m working closely with andy from autolinkuk.uk in southhampton upgrading Mk2 parts onto Mk1’s and The strong well made parts off the Mk 1 to Mk 2’s and this one as us both beat.
We think that you have to fit something in line that picks up the signal from the switch which then tells the relay and the lights work???.
The Mk 1 Mk2 switch’s are all rocker type, where as the Mk2.5 are not, but i do not know what i need to add also for it to work, i have gotten my teeth into this and will not give it up until it works (you understand) other things on going are rear speaker on to a standard jdm Mk2 bose system???A Mk 2 wiper motor onto a Mk 1 ,the list grows, just ask Andy.
The off/on/off type switch controls a fog lamp control module. It’s all about the fog lamp switching itself off on when you turn your lights off. You’ll either need the fog lamp module off teh car the switch came off or make up a circuit yourself that controls the fogs.
This is like the Twilight Zone! I’ve just bought one of these same switches yesterday and have been scouring the internet trying to find info on it. Yup, I’m trying to fit it to my Mk1! Both of us within a day, and this is about the only posting on the whole internet discussing this switch!
What are the chances?!
I’ve had the same WTF moment when discovering that one side is a rocker that springs back. Form what I can gather, this is the same process as the Mk2 fogs (am I right, Mk2 owners?). How does this work on a Mk2, can anyone tell me? Do you click it one way to turn them on (how do you know they are on?) and another to turn off, or do they turn off when clicked the same way as to turn on?
The other side is self explanatory - it’s your standard fog switch with built-in light.
I am going to Mazda tomorrow to talk to their mechanics to try and get a wiring diagram or something. I’ll let you know how I get on.
Wayne - I was down at Autolink on Monday buying some bits from them… what are you putting in your Mk1? I’m currently trying to retrofit a Mk2.5 speedo unit into mine It’s a headache, but I know it can (and has) been done. I’ve already got the full 2.5 interior and working on the central locking from a 2.5 also. It’s going to be a long summer!
Thank god it’s not just me,lets master this together,let me know what mazda say knowing them they will want ££££££ just to talk to them???
It’s nice to know that some one on here likes to get there teeth into something and not let go until it works challenge over “NEXT”
Andy is watching this one to see what happens,i was not holding any faith on here to be trueful unless you want to talk about bigger speakers or how shiney my car is using x product???not my thing been there long time ago???
I believe Mr walton is the man in the know,my main man andy tells me so.
The up grading with andy with swapping parts is mainly to see whats compatible with each model to make them better than they are,if andy has been asking for something and is not to sure if it will work or i want to try something with running and owning a Mk 1 and Mk 2 i become the guinneau pig or the poor cars do???
I remember your car from andy and julian and the prob’s they were hitting with the wiring but glad to know it worked out fine I can not fault autolink they are the most patient chaps i know and have got time for eveyone,i took my cars to the spring rally for his stand it was nice to see faces to the voices at last.and if you reading this autolink one hell of a big thank you form me.
Gareth it’s nice to know i’m not on my own and thanks for replying.
Perhaps if you don’t insult people you will get a better response[:|]
I think the fact that you can find no record of it ever being done before online, and that the person who sold you the part (who is normally very knowledgeable) doesn’t know, suggests that, maybe, perhaps, just possibly, it might not be a very common modification. Even if people have done it, from the sound of things, it is not going to be a quick explanation, and after being insulted, they might not be too keen to explain it [;)] - just my two cents…
Mazda dealers in my experience can be very helpful, but I don’t think they could help in this case - a competent auto electrician would be able to make up the control module you need.
I am entitled to my opinion,freedom of speech and all that,so put your dummy back in, i get a lot of mx-5 owners coming to myself after getting ripped off by mx-5 dealers/repairs and i pride myself on my standards and anyone who has used my services will tell you the same.
I know this is not a common issue that’s why i’m asking for help if you do not want to help fine i will work it out in the end and then help someone who needs the info from me which i will be more than happy to give.is’nt that why you have created the forum for,but i don’t get that feeling until today???
Lets see how many mx-5/roadster owners get involved now you state that i’m insulting them all???
You are indeed entitled to your opinion, I never disputed that, but that does not excuse what you have implied.
As an administrator I take great pride in the forum and the service that it provides, and when somebody starts insulting members, whether collectively or as individuals, I have a duty to intervene. If the tone of the forum is lowered to the level of some of the comments in this thread, then people will leave - there are plenty of options out there, and if they do leave, then nobody will get their problems solved, even if it is what polish to use.
I don’t think you honestly believe that I have lowered your chances of a response, but I appologise if that is the case - it was certainly not my intention, but I would like to ask you to do one thing; re-read some of your comments with either my eyes, or a fellow member’s eyes, because I assure you, you will see where I am coming from.
I don’t want to derail your thread, because then you will never get a response, so I suggest that if you see fit to continue this discussion with me, you do it through the Private Message system.
The one in the top left is the standard fog switch as sold by MX5parts.co.uk and other retailers. It has two positions… clicked on or clicked off and when on has a light on the switch which lights up red. It has the following pin layout:
The switch in the bottom left is another fog switch I have from a Mk2. This switch has one position (as you see it in the picture) but can be ‘rocked’ either left or right, springing back to this default position once you remove your finger. It does not have a light on it and I have no wiring diagram but the loom from which I got the plug has three wires (aside from lighting for the picture) - green with black stripe, Purple with yellow stripe and pink with blue stripe.
I have no idea how this switch is meant to work - does it push one way for ‘on’ the other for ‘off’; what a happens if you push it to the ‘on’ position when it is already ‘on’; and how does one know that the actual fog lights are ‘on’ if there is no light on the switch?
Does anyone have a wiring diagram for it?
Finally, I just got fold of the switch on the right this week. I had hoped this would be my saving grace - a double fog light switch (I’ve run out of space in the dash for switches!) however when it arrived, it turned out that both switches are different.
The switch on the left of the double unit has a light to indicate ‘on’ and can be clicked to an ‘on’ position (in) and clicked to an ‘off’ position (out), however the one on the right of the unit has no indicator light and simply pushes in, only to spring out once you remove your finger.
I have no wiring diagram for this switch nor do I have any information about the plug for the back of it, although the plug looks identical to the heated seat plug which is a similar switch.
Any help would be greatly appreciated. I am heading down to Mazda this morning - my local dealership is very helpful, friendly and more than willing to answer questions on my ongoing project.
The last (dual) switch is the same as in my mk2.5 sport with front and rear fog lights.
The left button with the indicator is the front fogs, and it latches mechanically.
The right button is for the rear fogs, there’s an indicator in the dash. I don’t remember whether it latches, from what you describe it doesn’t which suggests it uses a relay somewhere to toggle between on and off.
I guess it is this way because most cars don’t have the front fogs, they are an add-on for the sport model (and some others), whereas the rear fogs are standard.
Thanks Andy, so it simply presses in once for on and once again for off and there is an indicator in the dash - is this in with the speedo/rev/oil dials?
I’d still love to know what the other fog switch does, I guess the same thing but why does it rock both ways?
Yes. The rear fogs indicator is in the rev counter, bottom centre on mine. The switch doesn’t latch, it’s push on/push off, it must use a relay The front fog lights have no indicator in the dash, only the one on the switch.
I’ve wondered for some time why the two were different…
My best guess for the rocker switch is that it’s similar to the rear fog light switch and works with a relay, but you push it one way for on (close the relay) and the other way for off (open the relay). In the middle it does nothing and leaves the relay in its current state.
Ah yes, I can see that in my Mk2.5 clocks if I take out the bulb and hold it up to the light.
Does anyone know how this works in a Mk2.0? The wiring diagrams I have for a 2000 Miata have a standard on/off switch there… maybe this was just an EU thing as fogs are optional in the US.
I have an update on the spring back side on the switch from a auto spark friend of mine he as told me to get from MAPLINS a latch relay??? so it picks up the message from the switch and then onto the light relay??? item No:-N38AW ???don’t ask me how it works yet until my friend comes down, but i am away for a week from sunday so can not do anything until i get back???
In the mean time if you work it out please let me know,but watch this space.
I can’t offer advice about subject
I know nothing about, but there is no need to insult me about it.
However sticks and stones and all that, so I will offer advice where
I can.
The bottom left switch looks like
a rear fog light switch to me.
I do not know how the wiring
is connected, but
That is correct, there is no
effect off pushing it the same way twice.
The rear fog lights must be
connected to the headlights such that the fog cannot be left on if
the lights are turned off. The same applies to turning the engine
off.
I do not think this is the same
for the front lights, certainly wasn’t a few years ago, which is why
they can be latched.
OK, some progress. I have spoken with Roadster Robbie who has been a great help at sorting out the wiring for this dual plug and some details on how it works.
The on/off switch is for the rear fogs and this has a bulb in it to tell you it is switched on. The other push-button switch is for the rear fog light and this is indicated (as mentioned in a previous post) in the instrument cluster when on. At the back of the plug there are the following pins (as you are looking at it):
1 _ _ _ _ 2
3 4 5 6 7 8
These correspond to the following Mk2.5 wire colours and functions:
1 - Grey/Red: illumination for dashboard instruments
2 - Red/Black: illumination for dashboard instruments
3 - Green/Yellow: this is to power the bulb in the switch to tell you the front fogs are on
4 - Black: earth for the front fog switch
5 - Blue: this is ‘live’ when the switch is ‘on’ and goes to the front fog light relay
6 - Yellow/Red: this ‘live’ when the switch is on and goes to the rear fog lamp control unit
7 - Black: earth for rear fog light switch
8 - unused
The rear fog is controlled by the rear fog light control unit (possibly a latch relay type unit, similar to that which Wayne has indicated). This unit keeps power to the lamp when receiving a single signal from the switch and will cut it after receiving another. I think with the latch relay, a similar system could be retrofitted into any car using the dual plug. Power will have to be found to power the relay and a connection will have to be made with the fog light pin in the instrument cluster, to light it up when the switch is on.
I’m off for a week also so won’t be back on this for a while but I’ll keep everyone updated with the progress as I’m sure this switch could be of a lot of use to many MX5 owners and there is currently no documentation online anywhere (that I can find) on how to get it to work!
Both of us within a day, and this is about the only posting on the whole internet discussing this switch!
