Well after a hit and run I have had to replace one of the rear light clusters.
All the wiring had to be stripped back to the basic fives wires
Black earth
Blue indicators
Red brake lights
Yellow side lights
White reversing lights.

The question is where has the fog light wire gone

Or is the white wire used for both the reversing light and the fog light ….

Is this on a motorhome conversion, or a basic Fiat vehicle including PVC, with original Fiat wiring?

. swift motorhome. I think it could be a standard wiring for them as the fiat ducato van has the same wiring. But an extra grey wire
That I suspect is connected to the white wire as it does not have a grey wire 300 mm or so further on. Just the 5 wires

x230 or x244 base model? x244 was introduced in 2002, but a 2003 MH could be either. Wiring is different between models. If not sure see first 3 numbers of VIN. Also x244 has reverse next to first gear selection.
 
It’s a 244 DUCATO 15 JTD MWB
First the numbers of the vin. ZFA24400007xxxxxx
Sorry for the delayed reply. I have been busy outside clearing leaves out of the gutters.

For x244, from eLearn diagrams with colour codes translated.
LH rearlight Yellow/Black
LH indicator Pink/White
LH Brake Red/Black
LH Reverse White/Red
LH Rear Fog Grey/Blue

On the Ducato base vehicle the earth connection is local to each rear cluster. Are you sure that your black wire is an earth cnnection? I do appreciate that a separate earth wire is required on MHs, due to the use of non conducting materials in their construction.

Yes black is the earth

As above that’s 6 wires I only have 5 wires to either side.

Still guessing the white wire has two uses I will try today .

THINK! That will not work, you will just have two lights illuminating together.
 
Just a thought. Does your MH have a LHS rear foglight? A possible arrangement could be RHS rear foglight, LHS reversing light.

The reversing light was on the near side rear a white wire
The off side was the fog light again a white wire
When I put it into reverse both with wires are live.

But when it’s not in reverse I thought the wire could be used for a fog light.

I am now thinking maybe the off side white wire could be used as the fog light
If it was not connected to the light cluster.
I will do some testing this after noon .

Hmmm yeah it is a challenge ent it . I had exactly the same problem on my Hymer based motorhome . It's actually a left hooker , but no fog light on the right hand side . Yea i lost mine during the rip apart , as the wiring was quite rough and needed replacement . Under the Construction and uses act , the law states that a single fog light must be placed on the off side of a vehicle in this country , and i surmised a similar law in Europe , who i'm sure you will have noticed , drive on the wrong side of the road . The reason why the foglight is on the nearside of a foreign vehicle .
Okay so enough pratting about already . The foglight wire is actually on the nearside of the standard Duke loom , you simply need to run an auxiliary wire across to the right hand side of a UK registered vehicle . I can't remember the colour , but as this area is not yet complete on my vehicle , i can check if needed . Just as a note , vehicles of this age are not required by law to have reversing lights , but are often fitted anyway on the nearside , i believe the opposite to be true on foreign vehicles .
I upgraded to twin foglights , fitted in new clusters on a motorcycle rack , plus renewed both my original van mounted clusters with twin reversing lights , which required a two core cable run behind the rear bumper between the original clusters to carry the extensions . This allowed me to tidy up the rear end , and lose a single aftermarket foglight fitted to the off side . I actually had three foglights (two on the nearside) and two reversing light , a complete a mess .
 
Sorted Thankyou member. communicator
The white wire there are two of them a long way up the wiring loom

All the other colours there is only one of each At the back of the van


The red /. Yellow. . / black ../ blue then are joined together to split both ways to both light clusters. But the white wires one goes near side the other offside.

The off side one IS for the fog light
The near side is for the reversing lights.

However both have a reversing light in the cluster so a link was made from one to the other so both reversing lights were working .
The white fog light wire was still connected to the non working reversing light.

The reversing lights still work now the white wire to the off side has been cut.

So the white was not working on the reversing lights
Hence having tested it with a bulb it’s the fog light.

I am so very great-full to all the members that have helped with there Imput

Thankyou all again

Now have twin reversing lights. And will soon fit the fog light
