Can anyone give me in simple terms how To install a fog light on my n/a along with switch etc? What's the easiest way for a novice please

Good morning Jamestarin,

The best way, if you don't want the horrible single fog hanging on the underside of your Z?

Do you have front fogs?

Yes have front fogs

Then you can use that switch & run a feed wire to the back & convert one side or your reverse lights as a rear fog.

I have a separate switch located here

And here are the rear fogs?

You can get the red bulbs on eBay

Hope this helps?

There are several other ways to do it!

The switch has to be illuminated and the easiest way is to tap into the side lights power feed on the right pod.

 

Run a live wire to the rear and up to the right side reverse light as above, use a separate bulb hold or cut off the

one that's there and ground one side to the chassis.

 

Get a fog switch like below and you need connect the live from the side light to one prong, a feed to the actual bulb

and ground the last; that way when the switch is on the light illuminates too.

 

What are the legalities behind using the main fog light switch which controls the fronts? Can you not spur off of that so that when you press the switch, both front and rear come on at the same time.

 

As far as I am aware, front fog lights are not tested for at MoT time, it's just the rear.

 

If you want to avoid having to drill through dash plastics and/or have an ugly rocker switch staring at you, wouldn't it be a nicer way of doing things?

 

I'm asking as I don't actually know and want to do away with the rocker switch in my car.

 

I never use my fog lights, but when I do on the Merc, I use them both at the same time.

I think its fine for the MOT using the front fog switch to power up both, I've seen many a post recommending doing it that way.

 

Personally I prefer a separate switch and the small round ones shown above can be put on the inside of the pod and is fairly hidden.

 

The switch can be hidden out of site as long as at test time you inform the tester where it is and that its is still illuminated.

Since I never use them, I think I'll just wire them directly to the front fog light switch. I only have them working for MoT time as having 2 reverse lights is far more beneficial to me. I swap out a bit of harness and a bulb.

 

Now to find the wiring diagram for the switch pod! Anyone know which colour to use?

I know exactly what you mean, and ive got led's for my reverse and fog lights.

 

zedwizz made them for me about 4 years ago so the colours are even and inline with the other lights.

 

So when my rear fogs are on its both upper sides are lit.

Like this :

 

I've wired it into the front fog relay on both the zeds I've had, never had an issue at MOT time. Can get the wire into the wing nicely from the fusebox

Not sure I want to be running wires through the bulkhead unless I have to. I'll probably spur off the switch, just need to know the wiring diagram.

I ran it through the usual place through the grommet in the sill, can't see it unless you've got the arch liners off so I can't say it bothers me! Will have to put wires through there if I put any audio stuff in anyway

Right today took the car apart to put in new interior found a single wire going from the rear lights to a switch under the dash but then the wire ends there doesn't go anywhere else any ideas could this have been for the fog light at some point?

trace it back to the bulb and check the colour of it.

This is exactly what I've done. I need to get the clusters out soon for something so I'll look at the wiring and let you know what to splice into. I don't have front fogs, my side lights are mounted through the fog lamp hole!

could this have been for the fog light at some point?

 

Does sound like it, at the cabin switch you need that wire, plus a ground and then a wire that taps into your side light circuit which is usually a red/green wire found in many places.

 

At the back of the car use that wire which is your 12v and use it to light up a red bulb in the reverse light chamber - offside, you'll probably have to sever the reverse light wire, white/green i think it is and at mot time just connect that fog wire to that offside chamber, putting in a red 21w bulb of course, swap back once you've got the ticket but that part is up to you.

 

You could use one or more of the stop lights which are already bright enough and red.

If I connect the one end of the cable to either stop light or reverse light the other end goes to the switch where do I connect the switch to to get a live

 

Thanks for all the help everyone kinda determand to get it's mot and get it on the road for summer

the other end goes to the switch where do I connect the switch to to get a live

 

One switch spade goes to ground, one to the back of the car and the final spade - your 'live' to any sidelight wire, live therefore when you turn the dial once or put on your front fogs which if you didn't know turns the sidelights on as well.

Its perfectly acceptable to utilise the front fog switch to power the rear fog for mot purposes, and i think its the neatest and best way to do it.

 

You cannot however use your right hand stop light as a fog light.

could i use the third brake light located in the spoiler as this is not wired in yet?

And why would this be Chris, don't think it adversely affects another light, you could still keep the two outer stop lights for mot time and have the r/h fog either on it's own or both the inner stop lamps as fogs.

Think I misunderstood you then mate, if the current bulb is not used as a brake light and used as a fog instead then yes your spot on. I was thinking you meant doubling it's use as a brake and a fog light.

On another subject my indicators in front bumper aren't working bulbs are new and reading with multi meter in have power between 2 and 6 v is this normal I would imagine a fluctuation due to lights on lights off but thought there would be 12 v

No it's not normal, you'd get 12v whatever else is on or not on.

 

Your hazards work ? If so check again with that multi meter for your own piece of mind, which does leave me to ask.....are they filament type bulbs as opposed to led/smd type ?

Plenty of charge in battery ?

The indicator relay is up by the pedals fyi.

Any butchering gone on with the wiring ?

Sometimes a side light feed can be taken from the front fogs and moved to the indicator, so check what is going on, remove tape completely if it's there.

Sounds like one you might have to solve yourself.
