Hello,
Since I have already received detailed help here, I would like to give something back! I retrofitted rain and light sensor WITHOUT CHANGING THE WINDSHIELD!
Wiring loom RLS:
I built the wiring loom for RLS by myself, because I still had wires left over.
1x 0.5mm2 red/white
1x 0.5mm2 brown
1x 0.5mm2 violet/yellow
1x 0.35mm2 grey
Plug RLS VW 1C0 973 119
RLS VW 5K7 955 559
Holder RLS Aliexpress
Gel film
Light switch with automatic function
Connection RLS -> BCM
G397 Pin1 -> T73b/39 red/whiteKl30 or SC53
G397 Pin2 -> Ground brown near unlocking engine hood
G397 Pin3 -> T73b/24 violet/yellow
Light switch -> BCM
T10bb/2 -> T73a/37 grey
How it looks after installed RLS holder
It is important to stick the adhesive film of RLS holder onto the window first.
Only install rls after 24 hours!
The following must be coded for the RLS in the BCM with VCDS. In addition, I increased the lighting duration for the LH from 15 seconds to 30 seconds
Everything works perfectly, including leaving home, automatic driving lights and automatic wiping when it rains.
