Guide:- Connecting Fogs To Come On With Main Beam.

29th January 2009, 01:06

The principle is simple this will enable your fogs to come on with you Full/ Main beam for that little bit of extra light on the dark, bendy country roads

The fogs can still work without your main beam for when it really is foggy, and you shouldn't get in trouble if you don't go driving past people with your main beam on.

Things you will need to do this is:-

1.Wire of a suitable amperage, i used 17amp cable in 3 colours blue, red and black to make this simpler.

2. A relay to control your new circuit (Can get them from halfords £5/6)

3. Pair of wire cutters wouldn't go amiss either along side a soldering iron if you want to do a proper job

So this is what you circuit is going to look like,
http://www.accessconnect.com/images2...%20install.jpg

I drew out a more simpler and easier to understand version though to help myself a little bit,

How to wire it up.
The first cable will connect to you battery and tho the relay at the prong marked 30, this will power you fogs. This can be connected to the battery terminal on the top of the battery or in the little fuse box above the battery like mine,

The next wire is a Ground/ Earth. This will go from prong 85 to and earth point on your car and will simply just form the earth for the current to flow through the relay from the main beam thus forming a connection of power to fogs.

Next job is to ad your new power cable to the fogs. this is done by finding the positive power cable leading to the fogs just before the connecting plug (behind front bumper passenger side) the colour is yellowy orange if i remember correctly. Simply strip the wire of its insulation and connect the new wire to this cable. This then connects to prong 87, now you have successfully created a 2nd power source to fogs allowing them to be turned on via main beam or normal fog switch.

Not the best picture but you can see where the blue cables joins to the existing positive feed to the fogs in the bottom right hand corner and is recovered with insulating tape.

The last cable needed to be connected to your relay is the main beam feed which will activate the relay causing the circuit to be closed and the fogs to be illuminated. this will connect to prong 86 and can be connected to one of two places:-
1. Under the steering wheel where the main beam cable comes off the stalk.
2. on the plug to the plug that connects to you headlight bulb.

I connected mine to the plug on the bulb for easiness.

Either of these allow a current to flow through the relay from 86 to the earth on prong 85, thus starting the electromagnetic to connect prongs 30 and 87 together illuminating the fogs.

The relay can then be placed in the fuse box under the bonnet for tidiness and all wires threaded through into there. it also sits nicely in one of the holes already there.

Now just side back end enjoy that extra light on the dark country roads

Hope this guide helps some people, and if anyone gets stuck feel free to ask for help

M.O.T time simply connect a switch up to any one of the cables leading up to the relay to stop the circuit being complete, causing normal operation to be resumed

And for people who think this isn't a good idea don't post in this thread. This thread was created for the people who think it is a good idea therefore your opinion is not needed and the subject is not up for debate.

Once again hope this helps
Cheers
Andy

nice thread

29th January 2009, 01:11

will that pass an mot?

29th January 2009, 01:13

Not left how it is but a switch could be added to any one of the cables leading to the relay to stop this circuit eing complete therefor normal opperaion would be replaced.

29th January 2009, 01:13

good guide mate.

I owe you thanks x

edit: tad-dah

29th January 2009, 16:48

Nice one! good guide mate i will be doing this soon! Thankyou Thankyou Thankyou!

29th January 2009, 17:40

Its a good guide,but i dont see the point in it.

And you can be fined for driving about with your fogs lights on when its not foggy.

As said they only come on with your main beam and you don't drive past people with that on do you?!?

This thread is for people who think its a good idea and think its worth the unlikely risk of getting done for it and i also stated that this is just a guide and not a debate about the idea of it.

Cheers guys! If any one gets stuck don't hesitate to ask

29th January 2009, 18:07

My lights are doing my head in on my saxo. Side lights work, and passenger dipped beam. Ive replaced the drivers side bulb, with 2 or 3 differnt bulbs. However i cant get the dipped beam to work, High beam works fine tho.

So im having to drive with fogs on until i come to a car, turn them off n only have side lights on..

29th January 2009, 19:26

legend. at last some one has made a guide. i dont understand it 100% which is bad considering im doing and advanced electronics A-level which only 200 peeps in the country do, so i shud rele know how this works

edit: re read it and i understand it now. so basically; relay, 1 lead from relay to battery via fuse, 1 to ground, 1 to + on main beams, 1 to + on fogs? yeah?

29th January 2009, 19:45

nice guide mate

Thats the one bud just four wires basicly! haha i loved doing it as a did gcse electronics, felt like a plast from the past lol dead easy though hardest part is wireing to fogs as you have to get under the car to get to the wire them.
Let me know how you get on mate! i ot some 100w fog light bulbs also they they nice and bright

29th January 2009, 20:13

haa good old electronics lol
yeah i have some of the ice/cold blue or w/e its called bulbs, the white ones with a slight blue tint. they're pretty good. for the 'MOT switch', does it go on the wire from the battery to relay yeah?

29th January 2009, 20:24

Nice clear guide there mate

Could go on any cable i imagin mate because any one on them would cause the circuit to be uncomplete, maybe the feed from the main beam could be a good cable as it hasnt got a large current runing through it

Wicked thread mate, will deffinately be using this!

1st February 2009, 17:01

I done this today. only took about 2 hours lol in the freezing cold and snow!

Thanks for the guide it helped a lot!

17th March 2009, 17:08

I'm guessing as I don't have fogs already wired into the car. I can still copy that but making sure I earth the fogs and they will come on when I put full beams on??

17th March 2009, 20:02

Yes mate. you just wont have the ability to turn them on with dipped beams on. Dont need them on then any way so it is fine! Definately worthwhile doing its awesome for country lanes.

17th March 2009, 21:56

awesome m8. am goin do that at weekend good job.

17th March 2009, 22:06

Cheers bud, were bouts you from exactly?
Andy

17th March 2009, 22:21

ma 106 gti foggies came on with full beam and passed a mot no problem. so don`t think it matters. all the gti`s do this.

17th March 2009, 22:38

Gtis have driving lights not fog lights

17th March 2009, 23:18

Ideal, i shall be doing this tomorrow when i get from work. Cant see it taking me longer than an hour, got a connecting block from the doner car just got to go halfords or motorworld and pick up the relay. ill post some pickys aswell for the hell of it

is there really that much diffrence in them ? could you not to say to the mot guy if he said anything . there driving lamps. because the police thought mine were fog lights when i got pulled

17th March 2009, 23:35

They direct the light beam differently, don't know if MOT testers check the beam pattern on them or not tbh?!? imagine you could get away with it in most cases though

Andy

17th March 2009, 23:50

good thread.. gonna try this tomorrow.. cheers mate

18th March 2009, 00:01

good guide

although illegal, and i dont see whats so hard about flicking another switch to turn your fogs on tbh!

18th March 2009, 00:11

Cheers,
Because you would be forever flicking them on and off when you see a car coming the other way, easyer flicking one thing once than two things.
Just makes it easyer for people to do who who like the idea

fair point

what does the law say about this? just curious

18th March 2009, 00:16

No doubt illigal, infact i know it is as your not meant to drive with you fogs on unless visability is under ??? meters.
But aslong as you dont drive past people with your main beam on (which you dont) you should be alright as no one will know they were ever on.
Andy

18th March 2009, 22:30

Its not actually illegal. I talked to a copper about this for a while and basically the only reason you would get pulled and booked for is if you had your full beams on driving towards you will get done for driving without due care and attention.

As long as the fog (driving lights) go off when you switch back to dipped, your fine.

106 GTi's have driving lights where the fogs are. 205 GTi's the list goes on!

If you did get pulled all you have to do is prove that the lights turn on and off with dipped and full beam and the only reason you would get pulled is if you were driving around town like a twat with your full beams on because it looks 'cool' or not switching to dipped when there's an oncoming car which is the 5-0

Also the bulbs should be no more than 55/60w

Easyest way to tell if a bulb is legal is to see if it is E-marked, if it isn't chances are its not and should only be used 'for off road use'

18th March 2009, 22:49

Instead of fitting a switch could you not just remove the fuse from the battery cable?

This would mean there no power to the relay therefore it won't work till the fuse is put back in?

Correct me if im wrong

James

18th March 2009, 23:15

Cheers for the info Crigsha!

and to jim bob you are correct if you disconnect any of the 4 wires leading to or from the relay will stop the circuit being complete thus stunning its operation and resuming normal operation

Andy

18th March 2009, 23:55

Cool just thought removing a fuse is easier and cheaper than sorting out a switch, also a fuse cant get knocked accidentally or short across

James

19th March 2009, 22:57

Done tonight, took an hour to do
I used the proper connector from the car I got the bumper so I didnt have to ruin the loop, plus it is was easier to wire it. I just earthed to the the earth point by the N/S Headlamp.
I took a picture on the way home on full beams.

BRIGHT is all im going to say!

22nd March 2009, 18:35

good guide mate!

22nd March 2009, 18:38

looks good! will it go thru an mot? or u gotta change it back?

22nd March 2009, 18:40

can u have the fogs on just by them selves ? (without full beam)

22nd March 2009, 18:41

sorry read first post and see you can

yea it should be fine.

29th April 2009, 22:29

Can this be done to any car as long as you find the correct main beam and fog wires?

James

29th April 2009, 23:20

Use proper ring crimps on the battery + and the ground - not just wrap the bare copper around the bolt and tighten it up, what a bodge

30th April 2009, 12:46

Sorry, what can i say i just mustn't be as professional as some, feel free to PM a mod and ask them to remove my thread full of shoddy workmanship

ferryhill, i never actually got time to do it until now, just a quick question tho fella. Does this setup mean the fog light switch will control the main beam as well as the stork? and do you also know any where can get switches, been to halfords and a1 motor stores durham, but there choice of switches are limited.

aint a bodge if it works mate

, good guide mate will do this to my 106 just need to find some fog light looms
