Yes, it came with instructions. Seeing how sequentials dont work, could harness just be installed incorrectly?

Harness should be straight forward. If it is not working its either incorrect codes or incorrect pins. Either way need to contact support or take pics and post here someone who is knowledgeable may be able to point out any pins that need to be swapped

If you put it in reverse, does the dynamic function work then? Sounds for me like Inner-Left and Inner-Right harness is swapped since reverse lights are permanently on. Does the reverse camera work at all?

Yes, reverse camera works. Just reverse light stays on all the time and sequential turn signals don't work (it's just solid turn lights).

Just want to share my experience purchasing mk7.5 euro tail lights from USP Motorsports. I must be very unlucky.
Purchased the set on 11/17/23. Delivered 11/25. I open it to find both corners of the outers are cracked. I inform USP 12/3 of the defect.
They say I can keep the harness and just return the tail lights and they'll ship out brand new set. Replacement delivered 12/16.
12/19 Tail lights installed and coding instructions were followed, but sweep signals would not work and reverse lights stayed on at all times.
Couldn't figure it out so took car to Eurofed on 1/3/24. Turns out USP sent the wrong harness. I reach out to them again; They ship out correct harness 1/9, but their processing team wrote the wrong address so package is lost. Contacted USP again and they shipped out another harness. Finally got everything to work!

2 months are a bummer yeah. From my POV, took the lights from eBay (original VW German dealer) , and a harness from zero815. Pretty busy guy and million thanks to him for helping me out. Harness couldn’t be more perfect quality wise, and with his coding instructions , retrofit was a piece of cake. Thank god there are awesome dudes like him out there. The result is fabulous. It is like they are truly factory fitted from a 7.5 GTI, on my TDI. Enjoy it to the fullest more and more each day
Вітаю.
Шановні колеги, прошу вашої допомоги.
Маю Golf 7.5 2019 року з Америки.
Задні світлодіодні ліхтарі, які я модифікував для Європи з жовтим поворотником.
При цьому проводка і мікросхема штатні, 4 контакти.
Щоб змусити їх працювати, я замінив контакт 2 на контакт 4 і закодував відповідним чином.
Після цього права нога працює нормально, а ліва ні.
При одночасному включенні гальмівного сигналу + лівого поворотника або аварійки сигнал гальмування блимає разом з поворотом.
Це все відбувається тільки лівою ногою, права працює чудово.
Перевірив проводку, поміняв фари, нічого не допоможе.
Проблема тільки в кодуванні
2-й стовпець мав кодування, а 3-й мав НОВЕ кодування

VW uses "Blinken links Hellphase" (=Power ON during turn signal) and "Blinken links Dunkelphase" (=power OFF during turn signal) to get the alternating turn signal mode. Sounds like the brake light is still acting as a "turn signal", but only in power OFF mode. Please check the following line in your coding. I have seen before that coding changes are shown in OBD11 but the BCM never really accepted them. You might want to re-do the coding for Lichtfunktion C20. Just select "not active" again, and write it again.
| Ліхтфункція С 20 | Блінкен посилається на Dunkelphase | нічний актив |
Дякую, вже пробував це зробити, але спробую ще.
Оскільки ви маєте рацію, здається, що я написав "not active", а блок все ще бачить функцію Blinken rechts Dunkelphase.
Чи можете ви спробувати зареєструвати Bremslicht у Lichtfunktion C 21?

You could set "Bremslicht" in C20, but w/ Dimmwert CD20 being 0 you won't have a brake light at all most likely.

Hey guys! I recently picked up a harness from an ebay seller in china, as I didn't feel like paying 200 dollars for the ShopDAP one. They came with very very basic instructions in Chinese and I'm just trying to figure out which pin each wire needs to go to. I have a decent understanding of everything up to this point. I've looked through several dozen pages of this thread and as it's 238 pages long, felt like it may be better asked here:
Does anybody have a simple diagram showing the connections between all 4 lights, specifically showing which pins correspond to which wires?
Many thanks in advance, will keep looking in the meantime.
Editing to add pictures/explanations:
These are the components that were sent. I really want to be sure of the pin positions before installing as I would like to avoid ruining the header. I've gathered this info through the Chinese instructions using Google Translate. Bonus points and my eternal gratitude to anybody that can help me make sense of these instructions and prevent me from regretting going cheap on these! I would have liked to go with ZERO815's harness, but he's not currently producing them.
Instructions:
Right Outer: Two main headers only:
Right Inner: Two main headers, two single wires with ends to insert into (I'm assuming) the right outer harness. Final wire leads to male 3-pin header:
Left inner: Two main headers, single wire with pin, two wires with male/female 3-pin headers, respectively:
Left outer: Two main headers, female 3-pin header, single wire with pin:
I'm trying to figure out what they mean by "T8/2" in the instructions. I do see that pin 2 on the left and right outer headers are free, so that's my best guess. Assuming that the left inner light wire runs to the left outer pin 2, right inner light wire runs to the outer right pin 2.
After that, this is my understanding:
-1 black/white wire coming from the left outer harness pin 1 (??)
-1 female 3-pin header also coming from the left outer harness pin 1 (connects to male 3 pin header on left inner unit pin 1)
-1 male 3-pin header coming from the left inner harness pin 1 (guessing this connects to the left outer female 3-pin header)
-1 female 3-pin header also coming from the left inner harness pin 1 (guessing this connects to the right inner male 3-pin header)
-1 male 3-pin header coming from the right inner harness pin 1 (guessing this connects to the left inner female 3-pin header)
-1 black/white wire coming from the right inner harness (??)
After searching all day, the two remaining items above still elude me. For the right side, I believe the wire coming from the inner pin 1 should feed to pin 1 of the right outer side. Does anybody know where the loose wire coming from pin 1 of the left outer harness should go? The pin 1 connection seems to be the common connection on all 4 lights that connects to the BCM. I've seen a diagram that mentions this connection should go to the BCM connector C pin 6. Do I really need to run this all the way up to the front of the car? How do other harnesses avoid the need to do this?
Edit: contacted the seller and he instructed me that I don't need to do anything with the pin 1 black wire coming from the left outer light. I'm not sure how that makes sense.

As far as I can see on your pictures the adapter harness is wired like this:
Unfortunately it won't work without modifications on a NA MK7.5:
- Cavity 8 (=turn signal on ROW cars) on Outer-Left and Outer-Right is not populated on NA MK7.5s. NA MK7.5s use the brake lights as turn signals.
- BCM C6 (the black/white wire from Outer-Left) is already used for the little red side markers.
And now? There is a way to use the harness on your car, but it takes some slight modifications to the harness. Furthermore you have to connect the black/white wire from Outer-Left to the 12V outlet in the trunk (make sure you switch over the outlet fuse to permanent 12V). If you don't connect the the wire to 12V you won't have rolling turn signals. To finish the project you have to do some coding as well. Here is how the modified harness should look like:

I really appreciate the info ZERO815, your input in the past few years has been a huge help throughout this processs. Going to try to modify this myself, but ultimately got a refund from the seller due to the incompatibility. If I can't figure it out myself I'll just go with the ShopDAP harness.
Thanks again!
Thanks again!
