Put on the car but stuck with where the last two wires go in the adapter harness.

Golf 7.5 R
Hello everyone. I am a new user of this portal and I would like to apologize for my poor English ;). I live in Poland and I bought a Golf 7.5 R from the USA with OEM LED lamps. I would like to mount EU LED lamps with a fog lamp on the left side and dynamic turn signals (installation of such lamps as in the attached photo).
IMG_20230217_160048-forum.jpg

The lamps I bought have the numbers:
5G0945207G
5G0945208G
5G0945307P
5G0945308P.
I'd like to make the harness myself.
I found here a lot of information and different ways to do it, for which I am very grateful to everyone :)
My question is what wiring diagram will be most suitable for my car and coding?

Congrats on the new car. I would just buy the harness, they're $50-75 now and have instructions. If you do it yourself, it wont look as good.

ECS Tuning, shopdap.com, and a few others have them. Most will ship them to Poland. If you need someone to be your middle man and buy them and then ship them your way, I can certainly help out!

Cheers!

Yes, I am also interested in buying a harness (so it will be much faster and sure that it works), on the website you gave me for $ 199. If you have other stores that offer harness please let me know :) Thanks again for your interest and help

Talk to zero815. :) I bought a harness from him, and he's closer to PL than to USA.

hi, I searched all previous posts and found this instruction from Zero815 :) it is named as ROW so it should match🤔

That wouldn't work on your car. Yours is a MK7.5 US car, the diagram is for a ROW MK7 w/ halogen tails. There are at least 3 ways to solve it:
1. Adapter harness + coding (PM me if interested, shipping from Germany)
2. DIY wire flipping just around the tail lights (see attached pdf) + coding
3. DIY factory retrofit: run additional wires between tails and BCM + coding
In any case you need coding that matches your wiring. Otherwise the lights won't work properly.

ROW MK7.5 w/ factory fitted dynamic tails use light channel Leuchte27 to power the sweeping.

Depending on the harness you've used a different light channel is used for the sweeping. Check your coding for: LichtfunktionA16, 17, 20, 21, 27, or 28 = "Klemme15...", "Klemme30...". Replace that with the following value of light channel Leuchte27.

(1)-Leuchte27NSL RC6-Lasttyp 2736 - LED Kleinleistung
(2)-Leuchte27NSL RC6-Lampendefektbitposition 2700
(3)-Leuchte27NSL RC6-Fehlerort mittleres Byte DTC-DFCC 2700
(4)-Leuchte27NSL RC6-Lichtfunktion A 27Aktive Blinkfunktion hat ein auf 1 gesetztes zugeordnetes Bit in pa_dynamisch_blinken
(5)-Leuchte27NSL RC6-Lichtfunktion B 27nicht aktiv
(6)-Leuchte27NSL RC6-Dimmwert AB 27127
(7)-Leuchte27NSL RC6-Lichtansteuerung HD AB 27always
(8)-Leuchte27NSL RC6-Lichtfunktion C 27nicht aktiv
(9)-Leuchte27NSL RC6-Lichtfunktion D 27nicht aktiv
(10)-Leuchte27NSL RC6-Dimmwert CD 270
(11)-Leuchte27NSL RC6-Dimming Direction CD 27maximize
(12)-Leuchte27NSL RC6-Lichtfunktion E 27nicht aktiv
(13)-Leuchte27NSL RC6-Lichtfunktion F 27nicht aktiv
(14)-Leuchte27NSL RC6-Dimmwert EF 270
(15)-Leuchte27NSL RC6-Dimming Direction EF 27maximize
(16)-Leuchte27NSL RC6-Lichtfunktion G 27nicht aktiv
(17)-Leuchte27NSL RC6-Lichtfunktion H 27nicht aktiv
(18)-Leuchte27NSL RC6-Dimmwert GH 270
(19)-Leuchte27NSL RC6-Dimming Direction GH 27maximize

You can enable the sweep for turn signals, hazards and locking in 6 parameters individually (Active = sweep, not active = no sweep). If you search for "Außenlicht" on VCDS or OBDeleven please notice the letter "ß" is a special German letter that equals "ss" and not B.

GermanEnglishValue
Außenlicht_Blinker-Richtungs_blinken_linksturn signal leftactive
Außenlicht_Blinker-Richtungs_blinken_rechtsturn signal rightactive
Außenlicht_Blinker-Warnblinken_Zuendung_AUShazards ignition offactive
Außenlicht_Blinker-Warnblinken_Zuendung_EINhazards ignition onactive
Außenlicht_Blinker-ZV_Blinken_aufunlockingactive
Außenlicht_Blinker-ZV_Blinken_zulockingactive

On earlier MK7s - until some time mid MY17s - the sweep enabling is slightly different (on very rare MK7s it doesn"t work):

GermanEnglishValue
Dyn. turn signal modes-Richtungs_blinken_linksturn signal leftactive
Dyn. turn signal modes-Richtungs_blinken_rechtsturn signal rightactive
Dyn. turn signal modes-Warnblinken_Zuendung_AUShazards ignition offactive
Dyn. turn signal modes-Warnblinken_Zuendung_EINhazards ignition onactive
Dyn. turn signal modes-ZV_Blinken_aufunlockingactive
Dyn. turn signal modes-ZV_Blinken_zulockingactive

What is the difference between MK7s and MK7.5s? The MK7.5 (and probably late MY17 MK7s too) has one additional parameter:

GermanEnglishValue
Außenlicht_Blinker-Dynamische_Blink_Delayturn signal dynamic blink delay50 ms

With this "delay_parameter" the first blink during unlocking sweeps because it is delayed. On earlier MK7s the first blink is solid. I've tried many parameters on my own NA '17 GTI (Aug'16 built date) and with LichtfunktionA27 = "Versorgungsbedarf der LCM Module" it sweeps all the time. On my car "Klemme30G" is solid on the first unlocking blink. My assumption is that "Klemme30G" (switched battery) takes time to be turned on by the BCM while the first unlocking blink happens earlier.

Hi Zero,

I've set my hazards to "not active" so that they can be static, yet they are still dynamic. Any ideas on how to fix? I have a 2017 mk7 with a late 2016 build date. Leuchte28 is set to Klemme30G if that makes a difference.

Thanks in advance!
