I figured out the pinout colour coding of the cable wires of the 12pin female molex connector as I got one in my hands.
Here some photos:

Please help with the colours of the wires for the female 6pin and female 7pin connectors.
Some photos please

I've found two guys in Poland that have the module ofr sale, asked if they don't have the connectors, or the looms, or some photos, but both replied that no.

From the module side we are fine as I already have in my hands the female molex 12pin connector with a few centimeters of wire and I can see the colours. I bought a module that had the female connector included with a few cm of wires.


The problem is to find a seller that has the factory tow bar with the two male connectors as per photos (6pin and 7pin )and the wiring has been cut after the male connectors without disconnecting the female connectors so basically the female connectors are included and we can see the colours and pinout of the wires of the female connectors.

Otherwise we need a very kind fellow forum member that has a ducato with factory fitted towbar and is willing to take some photos and post them here in the forum.

As soon as I have these photos, I will be able to make a proper wiring harness like factory.

Yes, yes. I thought they could also have the looms. But no.

Check those listings:

Perhaps you'll see the photos of the required connectors, perhaps you'll be able to see the colours of the wires. If not, send me which ones you need, I will ask the sellers to send more detailed photos. It doesn't mean they will, but we could try

I found these three which are factory fitted. However thee are all disconnected from the male 5pin and 7pin connectors, therefore there are no female connectors present. You can ask them if they can get the female connectors as well if they still have the van in the scrap yard. or if they can sell the rear wiring harness of the van if they have it.

I will ask in the morning. To avoid any confusion, can you please point the two connectors on one of the photos? it will be easier to understand and explain to the guys.

Thanks.

If you check the last 2 photos above, you can see the 6pin and 7pin male connectors from my towbar. These male connectors connect to the female 6pin 7pin connectors which I do not have in the rear ducato wiring harness of my van.

Similarly I have pointed out below in the following three photos from the 3 allegro sellers the 6pin and 7pin male connectors hoping they can help finding the female connectors I do not have. Please ask them if they can find them and send you some photos. I am willing to buy these connectors or the whole rear wiring harness.

Thanks to the new eLearn all Fiats including Ducato Euro 6 that a fellow forum member posted, I gathered some more information regarding the trailer wiring

 

[the green vanper]

Great, I've wrote the 2 guys as promised, but they have not replied. The Polish breakers rarely do I was ment to call them until the end of the week, as I'm busy with the job and the getting the info from the new eLearn And frankly saying I hoped that you'll be able to sort it with eLearn
