Fog light help needed!

Post Fri Feb 03, 2012 5:00 pm

Tried to fit some front fog lights to my '89 e30 but I can't seem to get them to work? Don't think it has ever had fogs before. The lights worked fine on my previous e30 so doubt its them. I plugged in the only wire that i could find free behind the head light which was one with a blue plug. I've read on here that it should be a grey plug but i cant see a grey one anywhere, and all the plugs seem to be different colours to the ones on the previous car? I have put 7.5a fuses in slots 29 and 30 in the fuse box and a black relay in the k8 slot. I presume the black relay is correct from pictures ive seen? The relay works in other slots so not that if its correct. I also put a bulb in the dials as it didn't have one. And i changed the switch to the double fog light switch. This switch also worked in the old car.

The rear fog works as normal but the fronts do nothing and the bulb on dash doesn't come on for fronts. Any help will be appreciated as i can't seem to find an answer on here already

Hi

ALL,

I am trying to do this also, mine is a 1.6i lux and I have also ofund a greay connector, it has .87v coming out when measured, but I think you need 13v or more. I have placed a relay in k8 and the dash buld does not come on, what can be done? this connector is on the driver side behind the front head light, or between the windscreen washer tank and head light.

ALso on the other side in the same place there is a round two pin connector- what is this for?

Many thanks

Manni

Hi

Guys these are the connectors I am talking about.

And

Thanks

are you sure the double switch works ok,you do have a double switch i take it

Post Fri Feb 03, 2012 6:54 pm

Hi

If the double switch your referring to is on the dash, right of the steering wheel, then no, it is a single rectangle switch, which turns on my rear fogs. But the fuse box has a k8 realy space vacant and you can see the pins also.

But what are the two connectors above used for?

Thanks

the plug in the first pic looks like it has a broken bit left in it

Post Fri Feb 03, 2012 6:56 pm

you need a double switch and another relay for front fogs m8

Post Fri Feb 03, 2012 6:57 pm

i have a double swich if you need one

Post Fri Feb 03, 2012 7:03 pm

Hi

MATE,

ok, IF i was to add a double switch and another relay, where do I get the connection from to supply voltage to the front fogs?, could it be the connector in the first pic, at the moment it delivers .87v when the rear single fog light is pushed in, what do you think?

THanks

the plugs you need are grey they can be a pain in the arse to find trust me but you deffo need a double switch and another relay for them to work manni

Hi,

Thats fine regarding the plug, but do you think the connector in the first pic is the one which will connect to the fog lamps?

Thanks

thanks

This thread is confusing, because two people have posted with what they think is identical problems, which in reality may be completely different.
However: The wires to the LH foglight plug are brown and yellow/brown, and those to the RH foglight are brown and yellow/purple, so find plugs with these coloured wires!
Remove relay K8 and identify pins 30, 87 and 87b of its socket (marked on the relay). Use a short piece of wire to link together 30 and 87 of the socket. This should light both front foglights, and the telltale light on the instrument cluster.
If it does, remove the wire, replace the relay, and remove the foglight switch. Identify the grey wire to pin 7 and the grey/blue to pin 5.
Switch the ignition on, and use a piece of wire to connect the grey wire to a good body earth. The foglamps should light.
Connect the wire between the grey and grey/blue wires of the switch, turn the ignition on, and turn the headlamps on. Foglamps should light.

there you go manni

Hi

Brian, many thanks for getting back.
I am a bit confused now. my car did not come with any front lower fog lamps.
the fogs work,as i have a single fog lamp switch next to the round pull out switch for the head lights.

the only free connectors that i see are as in the pic above, the rectangle in the first pic is on the drivers side front and the round connectors is at the front on the passengers side.

only relays k3,4,6 and 7 have a relay, other vacant, by looking further at k8 it has pins in, so i guess it will take a relay.

So i guess my question is can i fit front fogs lamps to my car and if so, how?
thanks

Remove the blanking plates, remove the square plastic plugs that the screws fit into and replace with the correct ones for foglights, fit the lights, find the correct spare plugs to fit them, fit 7.5A fuses in positions 29 and 30, fit relay K8 (identical to K4), fit the tell tale light to the spare position on the instrument cluster, unplug the single foglight switch and fit the double button version in its place.

Post Fri Feb 03, 2012 9:26 pm

hi Brian, many thanks, now I have understood almost all of it, only one small thing - "find the correct spare plug to fit them" - is this the one in my picture above? becos when i push in the rear fog light switch it give me 0.87v(the plug in the first pic above), ? if so then job done, there is no other spare plug in that front area of the car. this is the only one, sorry just also realised I have tried pushing that plug into the front foglamp it does not fit- so where and how do i get power/voltage to the front fog lamps?

Also any ideas what the other round plug is used for in th second picture.

I am sorry Brian to be a pain, but i really need your kind help with this.
thanks

Thats your problem !!!!!

You need the double fog light switch........

Post Fri Feb 03, 2012 9:31 pm

Have you got one of these ????????

Post Fri Feb 03, 2012 9:42 pm

Hi

Kam,

Many thanks for your help, will this twin switch JUST fit in the single switches place? if so, the problem is still physically how do i get voltage to the fog lamps?

If the twin stiwch reqiuires extra wires ok, i understand that, then the extra wires will connect into the fog lamp and then i splice so that i supply voltage tot he other fog lamp.

I hope i a making sense here?

No i do not have the twin stwich, is this for sale?

thanks

Manni

Post Fri Feb 03, 2012 9:44 pm

No extra wires required, the wiring will be there, just swap the switches, Insert the fuse's and relay, and fit the lights......

Thats how i did mine.....

Plug into Foglamp

Post Fri Feb 03, 2012 9:59 pm

Hi

Kam, many thanks for this, I will try this tomorrow, but the only availble connector is the one in the first pic, there is no free similar connector on the other side. infact- there is a hornjust above the fog light in your pic on both side ( where you would fit the fog light) i think that is the connector you are referring to, but are then connected to the horns?

Thanks

Your 0.87V is presumably measured with a voltmeter on an unloaded circuit, so is totally meaningless!
All E30s left the factory foglight wiring, so look for the correct coloured wires.
Note that all I've written applies to UK spec. post facelift cars. Foglight circuitry varies for different markets.

Hi

Brian,

Many thanks for your reply, There are two connectors, one on either side behind the front valence. I can see a horn and behind the horn is the connector, i need to find out if this is connected to the horn, but access is from the bottom to these connectors, i mean are they justtied up doing nothing or are they connected to something, this must be the same on all cars which did not come with factory fitted fog lights?

I will post my finding tomorrow.

Many thanks
Manni

They're there somewhere, with nothing connected to them, unless someone has been handy with the side cutters.
What age/model of E30 is this, BTW?

Post Sat Feb 04, 2012 12:56 pm

Hello all,

I want to thank you all for your kind help.

I have found the other connecter for the fog lamp also, the one in the first pic was one of the connectors and other was in the same place on the other side.

all i need now is the relay, went to halfords to find one, but no luck, i know you said similar to the k4, ie black 5pin. any details on this?,
thanks i really appreciate your help.

did you get the double switch manni

Post Sat Feb 04, 2012 1:36 pm

Relay is double pole, normally open. It's the same as K4, so use a K4 from a scrapper, not some Chinese cr*p from Halfords.

Post Sat Feb 04, 2012 9:06 pm

All, I now have the switch and the relay, will fit this tomorrow hopefully the snow would have stopped.

But what is the round connector for in the second pic, thannks

Mannis problem is quite different to mine but i'll have a go with connecting a wire across in the fusebox. Pretty sure the relay is ok becasue it works fine for the wipers? Also my double fog switch worked fine in my last car, but i'll try check it some how. I'll check if i've got the right connectors at the fog end as i just thought mine could be the ones for the headlamp wipers as i dont have these either. The connectors i have connected atm had no blanking caps etc. on them so maybe 22 years of weather has buggered them a bit!

Post Mon Feb 06, 2012 11:41 am

Right i have tried brians method. I took the k8 relay out and connected 30 and 87 and the front fogs came on along with the light on cluster (but no rears if this makes a difference?). Put the relay back in. Earthed the grey wire on the switch and the lights came on again with ignition on. Then i connected the grey with the grey/blue and the fogs were still on with ignition. So i 'unearthed' the grey and the fogs came on with the headlamps on. At no time were the rears on but they worked fine with the switch as they should. And at no time could i control the front fogs with the switch, it was off the whole time i was connecting wires etc. Also the light on the cluster came on each time the fogs were on.

So basically the lamps/plugs etc are fine im guessing? Does this mean it is just the double switch that is broken? Or the relay? I have pictures if it helps?

Hope this makes sense...

Thanks brian
