Found a wiring diagram, look like it connects to the can bus.
VW calls these two LED strips L235 and L236, look them up on Elsawin.
Thanks for the diagram.
If only i have a Testing donor car
I think the Ambient Light will work best with MIB2 and MIB2.5
The connection looks simple.
can explain connection to me?
how do you even read those wiring diagrams? can hlep?
Two of the wires go to Power and ground, as it has to have power and ground to light up, the third one from what i saw connects to the can bus and is used to control the lights, pretty sure if its connected to the can bus then it controls the color and brightness.
well, one is power and you can see that B552 means - Positive connection 2 in roof wiring harness, the brown is for ground so the third has to go to the BCM.How do you see which one goes to the BCM?
So, to my understanding:
Pin 1 -> Pin 4 of B552 (roof wiring harness)
Pin 2 -> Pin 29 of T73B (Socket B of BCM0
Pin 4 -> Ground?
All correct ,If you can guys have a sunroof check If this wiring matches your car.
Now remember that this diagram is from a Tiguan, It Is not factory on a golf from what I Know, so The wiring might be different In the golf.
Is there a way to test if Pin 29 on Socket B does something when you move the slider on the MMI?
will the voltage change? It’s the best way to check itI think.
