Answer.- I am quite capable of making modifications, I have the patience and the desire, I have always achieved them with effort and perseverance.

Are you able to read wiring diagrams and distillate all needed info?
Answer.- It is hard for me to read Flowcharts but I can manage

Are you able to make your own wirings?
Answer.- If I have the pinouts and the guides well detailed, I can do the detail of why I want to echo the wiring looms, Automatic lights BCM that you had at the
The sale is because the connectors and the relays and relay holders come practically ready {the same as the originals} I do not have a part number for the spare parts of the relay holders
or the models of the dupon connectors and plugs of the wiring looms to do the retrofit.

I have the interior light dimmer and front fog lights installed from the factory

Do you have a system like VCDS to make changes to the codings and adaptations of your car?
Answer.- Yes. alternative version 23.3

Or do you need very detailed instructions on what to do and are you not able to work (semi-) independently?
Answer.- Generally I do things independently when I am beyond me and I have searched a lot and I ask for help.
In the same way, having well-detailed instructions eliminates the margin of error (I think)

The problem is going to be another one, my vehicle is an Amarok VIN: WV1ZZZ2HZCA026354

The Volksvagen polo and the Amarok share many things and there is the wonderful thing my request for help is because my Volkswagen is an Amarok and there is the biggest problem
I have studied a lot of polo things and the VW Trasporter are almost twin brothers with the Amarok in various electronic things

My problem is that it is an amarok. Retrofit there is very little information except to do what I want to do with this retrofit
I already installed some electric seats from an Amarok V6 ErgoConford and I still have to buy the connection branch for the heated seats and
Seat heater module that is the same as the Polo, they sell it on Aliexpress

I couldn't find the power branch for the electric seats. Meanwhile I have punctured the original cables so as not to cut the original plug
and to be able to move the seats and their regulations

I changed the instrument panel, mine was 2H0 920 853 B, I changed it for this 2H0 920 871 A, I had some details that I think can be fixed with VCDS
I have to install an oil level and quality sensor while deactivating the warning so that it would stop coming out, when I turn on the fog lights I don't have any witness on
the instrument panel or synoptic, I do not have an oil pressure witness or warning and the conford sensor for panel lighting works opposite { when the light hits it, the lighting of the instrument panel increases
And when it's dark, it only lights up the clock hands.... I think that will be solved by retrofitting the lighting and connecting the Canbus signals
to the instrument cluster when you install the new BCM}

I have saved the New BCM, not the one and installed 7H0937090D
I have saved the 5ND 941431 B XSH Switch AND THE PIGTAIL CONNECTOR
(They gave me the mirror and RLS sensor of an Amarok 2020, I don't know if it will be compatible with my Amarok 2011 to 2016 since in the VW Amarok 2020 it has another instrument panel)
I have a mirror and sensor (RLS) from a newer Amarok sensor part 5K7955559C - Volkswagen Rear View Mirror 3G0-857-511-AM or can I install it the same and it will work 100%?
o I have to buy the one that corresponds, which would be this:

I can send photos of what I have done so far and what I have gathered to complete the project or whatever information you need, I am at your service.


I am alone in this adventure because as I told you here in Chile, everyone says it cannot be done and I see that it is possible in other Volksvagens because in this one it is not.
When there are people who want to help or guide you, it can be achieved with effort to reach the goal

For anything like it's an amarok and not a pole, I'll understand if it goes against the principles of the forum to help me
Thank you very much IICHEL for taking an interest in my request for help anyway for anything.
I hope you agree to help me or enlighten me on this path.
Thank you IICHEL

There are a few problems that you must find a way to get over.
- Like you say, it's an Amarok, not a Polo. Still PQ25, very similar, but not the same.
- You are very far away from us
- ciclo is not selling the wirings anymore for BCM Max retrofit, but he is still the expert on this
- I don't know how to make them
- You will attempt to do two retrofits at the same time - BCM Max and automatic lights.

Some solutions:
First:
For the BCM Max retrofit it's probably best if you obtain the wiring diagrams. You will find them here.
From here it's very important to determine two things:
- What is my car currently equipped with? This will require your effort in making pictures and compare them to the wiring diagram.
This is for all wires from the light switch and dimmer to their endpoints and all external lights and their endpoints.
That's a lot of work. It must apply for every single wire and it must be exact:
All wires from light switch
Front: DRL, low beam, high beam, front fog lights
Rear: license plate lights, reverse light, rear fog light

The indicators, parking lights and brake lights are controlled by BCM anyway. You can leave them out your study. It will save complexity and time.

Here are some schemes:
2009-2015 https://drive.google.com/drive/folders/ ... drive_link
2016+ https://drive.google.com/file/d/1BUp_Ih ... drive_link

The next step is to determine how to convert to BCM 7H0 with all lights controlled by BCM, perhaps with the exception of high beams?
So you must get into the wiring diagrams again and determine how this would be in a car with i.e. PR-7L6, start/stop system.
This configuration controls lights via BCM.
BCM 7E0 can also control high beams via BCM, i.e. for high beam assist.

I think you will be able to do a lot of wiring in the area between light switch, fuse box and BCM.
But some will perhaps require you to run wires to reverse light, rear fog light, front DRL, front fog lights, high beams?

The next step is to activate the new configuration in your new BCM. The BCM must be coded to comply with the configuration and desires you have.
The expert on this is also ciclo. If he can help you out with coding, that would be very good.

In the meantime, you must determine if you want to first make the conversion from BCM 087 to BCM 090 and finish that, or to include the automatic lights.
The advantage of combining is, it's more efficient. The disadvantage is, it's more complex.

I hope you understand the systematic approach you must take.
I am sure it is possible in your VW Amarok, the only thing that needs to be able is you, and I hope this post is a good preparation on what to do.

if you're handy with wiring, i'd recommend you make your own.

the basics of every bcm max conversion is like this:
- make the correct inputs of terminal 30 to the bcm
- make the correct inputs from the light switch to the bcm
- make the correct outputs from the bcm to each of the external lights

sometimes you'll have to do some other wirings
- T73/4 to the instrument dimmer
- 2 new canbus wires to the instrument clusters, if you take a 7e0 bcm

unless you are ciclo, you probably dont get all the wires right the first time. you'll notice a light isnt on and you'll investigate.
i've done a few bcm max wirings for customers in my workshop, that usually went like that.
i never did it remotely and also not on a chassis i'm not familiar with, i never did an amarok. so i'm not very comfortable with making a wiring for you

i'm not able to judge your skill but if you are able to read a wiring diagram, add 1 and 1 together and you can make your wiring, you'll be able to do a lot.
and of course you'll need to have a diagnostic tool like vcds.

For help with any problem:

- Autoscan and clear images of the installed parts about which you are asking. On the PQ25 platform, the images are essential, for example, there are different fuse boxes depending on the year or place of production, etc...
- Only ask one question per post. Wait for a response (it is likely that the response will not be immediate). Then you can ask the next question.
I do not guarantee that I can answer all the questions, there are current circumstances that do not allow me to do so.

Any other means of communication other than the forum is not possible, my help is totally altruistic, so it must be shared with all forum users (and the rest of the world).
You can only contact me by private message in the language you prefer, but you must first post your question on the forum.

I just want to be warm and friendly, but sometimes it seems like I'm not. The time we spend on this has to be fun and enlightening.
