Negligence, is the right word for all the recklessness and irresponsibility committed in this electrical installation (like going back to the 20th century or worse).

No matter how much time I have wasted here due to these negligence, I did it all altruistically and with my best intentions, I am sure that many people will find this installation guide useful. I expected everything to end with a happy ending and it turned out to be a real disaster.
The latest images you post are creepy.

KamilPL, everything has easy solution, read the whole thread again, but this time I recommend that you pay close attention to everything you do, I will not answer any question that has already been answered or can be deduced from the diagrams.

Recommendations:
- Do not use the damn "Smart-phone" to view and manage the content of this thread. "Smart" phone is intimately linked to "Stupid" people, impossible to separate one from the other. Please, use a PC or laptop to manage the information for this electrical installation.
- Block the advertising that is generated in the text.
- Don't use that 'Electrician' ever again in your life.

Good Luck, it is in your hands, dexterity, intelligence, and in the use of suitable materials to manipulate automotive wires.

I wasn't sure, I preferred to ask and do the right thing.
I know that we lost a lot of time looking for electrician errors .... :(

4. T17 / 5 <--> T17 / 16 Bridge ready
3. Have the cable in the light switch connect to it (T17 / 13) (bridge) or remove and insert a new one?
1.It is possible that the original harness does not have this cable to connect to T73b / 7 because I cannot locate it, Ori bridge T17 / 16 <--> T17 / 5 link to the photo from 08/15/21 viewtopic.php?p=584960#p584960



I'm sorry. Cyclo, I'm a peasant from the countryside who doesn't know anything about car electrics and it's black magic for me, but with your help I can manage it, I use a laptop and google translator to communicate with you: P

2.Remove the original T17 / 13 cable and insert the new T73a / 45 &lt;--&gt; T17 / 13 or 1.T73a / 45(new) bridge &lt;--&gt; T17 / 13 (original)

In this case I will help you in everything you need.

I make you a proposal, what do you think if we do all this wire by wire? that is, choose a wire and until it is correctly installed, we do not go to the next one.
Is this good for you?

No matter how long it takes us, I am aware of your hard work as a peasant (priority number one), the little time you have available, the weather in Poland and other circumstances.

If you agree, choose one of the wires from the installation guide and I will guide you in detail.

I took time off on demand and I did not go to work today I hope we will be able to put it together today and check how it works

Since 5,4,2 are ready (OK) let's do -> T73b / 7

The bridge T17/16 -> T17/5
What cabling should I attach the cable to be in the BCM T73b/7, since it is not in the original harness?

I see another wiring error original purple / green T17 / 8 wire take it out and make a bridge to T17 / 9 right?

I will wait until it gets a little warmer, due to the fact that I do not have a heated garage, I do everything in front of the block, check if there is a cable in the bcm T73b / 43, if there is no cable T73b / 43 to T17 / 9, the bridge with the original cable and the T17 / 8 I will remove and will insulate

after solving these 2 problems, we will move on to the next, hopefully, last wire (problem)

Well, I have all the erWin diagrams for the Ibiza 6J manufactured in Spain-Barcelona (your Ibiza), and in none of them is it contemplated that the wire from T17/16 to T17/5 is RED color.

Taking into account that the diagrams may be wrong because we already have a lot of experience with these diagrams,
Are you completely sure that the RED wire from T17/16 to T17/5 in your Ibiza is an ORIGINAL wire?

I have an alternative solution for T73b/7, but I need your answer to my question.

At no point in this installation is anything said about the T17/8 wire, this wire should not be touched under any circumstances.
This green/purple wire should remain intact, as it is from the factory. It is the activation signal for front fog lights.

I do not know if this was the case in the original, I only have a photo from August 15, when I started to do with the car: P maybe the electrician added this bridge 17/5 -> 17/16 as he added front fog lamps

I'm going to the car soon, it will tear off the original insulation and check if the cable is still there, but I think it is not there

Ok, I don't touch it.
First let's do the T73b / 7, then let's do the T73a / 45 -> T17 / 13

Alternative solution:

T73b/7 is the supply signal for the license plate lights.

From the Dimmer an original wire was removed and isolated, the T6/3 wire (according my diagram for this installation).
Take this T6/3 isolated wire, strip the insulation, splice a new 0.5mm2 wire to this wire, and run the other end to T73b/7.

OK, I'm going to make cables for the car

Now explain to me exactly about the T17 / 13 -> T73a / 45

In the light switch I have the original T17 / 13 cable, bridge it with the new bcm T73a / 45 cable?

or remove the original wire from T17 / 13, insulate and add a new one from bcm (73a / 5) to the light switch (T17 / 13)?

T73a/45 is very important, it is the signal that activates the parking/side lights. (58 signal)

Make a NEW wire from T73a/45 to T17/13.
Isolate the original T17/13.

Depending on the model there are traps in this original wire that we dont need. (diode trick)

Remove the Blue, and White/Black wires that are cut but still attached to the T17 connector.
High risk of short circuit if you don't remove them.
