Cheers rich, think I need some help with this as I'm never too good!!

An Matt H that's the thing with flashing people out too it would be rather helpful!!

Anyone got a wiring diagram of a twingo..?
 
I've been having a look to see if it would be possible to do this within the cabin at the switch/relay areas. As this would mean the fogs and main beams could be still be powered from their original relays.

Unfortunately the headlight relay is the most inacesable and not even visible unless you get your head into the glove box. To make things worse, the Body ECU is blocking the way.

Getting to the cables at the back of it would be impossible without dismantling half of the dash :(

Lifting the storage tray infront of the steering wheel, there is reasonable access to the wires but they are all bound into looms and theres many wires with duplicate/similar colours so that could lead to disaster. The plastic cowl mouldings around the steering wheel clip together and are rather expensive if something breaks.


Doing it behind the bumper may need power feeds sorting to the new relay/s (maybe one each side) but access will be much easier once the bumper is off. Maybe a job for a dry day ;)
 
Nice one Neil appreciated I've not had time to stick my head under the bonet, but was wondering if you could link it too the spare connector which has been caused by the addition of HiDs

I had thought of that, but I'm tempted away from the idea of using the headlight circuit to power the fogs as well.

Both headlamps are powered from the same relays (one for dip, one for main) so with normal bulbs installed, the main beam relay has 2x60watt fillaments running of it. Adding another 2x55 watt foglights to it may overload the circuit.

It would be OK if the foglights were LED and the Headlights were HID 2x35watt. But LED foglights are going to be no good for anything but cosmetic looks.
 
I wonder if it wouldn't be better to convert the front fogs into driving lights. In the past 30 years I've yet to find front fog lamps useful, in any of the foggy conditions that I've experienced.
 
Sorted :cool: :mrgreen:

Whenever the main beam is on (or flashed) the front fogs illuminate. When the fogs are on, main beam is unafected.

1. Get the bumper off.

2. If these are going to work as secondary headlights, they may as well be adjustable (although I havent tried adjusting them on the car yet :? )the lower chassis rail is in the way so this doesn't work on a 133
2a. Left hand adjuster can be accessed through one of the gaps between chin spoiler and bumper

2b. Drill a hole to allow access to the right hand adjuster

3. The modification uses a 4 pin relay like this. (you could use a 5 pin relay but not use 87a)
Pin 30 brown-orange goes to the battery +12 terminal through a fuse
Pin 85 white wire goes to the headlight connector or splices into the white headlight main beam wire
Pin 86 Black wire goes to chassis ground
Pin 87 Brown wire (x2) goes to fog lights and splices into the beige wire near the foglight

4. Connecting up.
4a. Having a spare headlight connector due to the HID's not using the right hand connector, I plugged a spade connector into the white wire for the main beam (hence using a white wire) connected to pin 85 of the relay. If you don't have a spare connector, you will need to splice into the white wire somewhere convenient.

4b. Heres the right hand side foglight cable with one of the new (brown wire) feeds from the relay spliced in

I spiral swapped the cable up to the headlight connector and threaded the cables across the front of the car in a pvc sleeve following the existing loom.

4c. Same thing for the left hand side foglight power

The ground for the relay coil went to the chassis grounding point next to this connection.

5. Using an inline fuse holder, wire in pin 30 (my fuse holder cable was 10cm too short, hence the splice)

6. Mount the relay somewhere safe and fairly dry.

7. Insert fuse. Test :cool:

8. Refit bumper :mrgreen:

Edit
9. Being as adjusting from underneath with an allen key didn't work :(
9a. Wait for dark and find a level area so you can check the beam spread from the main/fog lights. (Having the main beam fully down using the dashboard switch will prevent the fogs pointing skywards with a load in the boot)
9b. Remove the 3 screws from the left hand arch liner (2 underneath + 1 at the side)
9c. Turn the steering wheel fully left which allows you to pop the liner enough to get your hand in. With the resonator box removed, adjustment is easy ;)
9d. Use a towel to cover the right hand lights so you can see the effect better. Turn the fog light adjuster to bring the beam up to give a reasonable throw of light, without it overlapping with the main beam.
9e. Repeat on the right hand side, which can be dangerous as the alternator belt is close by Stop the engine. It is also much more difficult due to the washer bottle, but can be reached.
 
singlespeed the guru strikes again :) awesome effort!! no point in doing this with led fogs though haha
 
It took nearly 3 hours, with one of those being letting my fingers defrost whilst getting the bumper to wing screws out/in. I took a while trying to decide the best route for the wires and where to splice in to keep the splices as dry as possible without needing to get into a large loom.

At least with LED fogs and HID headlights, you would give a definate flash from the LEDs whilst the mainbeam is still warming up.
 
Foglights adjusted up so they are lighting up a usable part of the road, instead of 10ft infront of the car. At last, candles have become usefull lights :)

It would have been much easier if the allen key worked. It may work on a GT as there looked to be a small cutout in the chassis rail which may line up with GT fogs
 
What grade wiring do I need to buy and all that???

I'm technically challenged!!!

I need a list!!
 
Just a word of warning If nobody has already ( sorry of they have)...
It is a road traffic offence to actually drive with fog lights on if it is not foggy... Most police officers don't do anything but you could get a funny one who would like to nick you for it. And if they found out its been hard wired into normal lights they can be even worse about it due to being an MOT failure and unroadworthy car.

Just thought I'd give a heads up anyway :) although nice going with it all! Sounds a pain in the arse to do though
 
being linked to main beam, I'd be rather anti-social by not dipping for anyone to complain about the foglights being on.

That's why Singlespeed only wired them to come on when high beam was on...

Ohhh that would be why I should read the full thing before posting. Oopsy

Also top of this thread is a long list of opinions about said issue, plus Road Traffic Offences im pretty hot on!
