в общем, попробовал я связаться с продавцом - получил такой ответ:
Dear Aleksandr,
Sorry for late reply.
We don't have the instruction for installation.
But we have the connection for the rain sensor and the mirror:
for rain sensor:
1# pin-------connect with positive electrode (SC17)
2# pin-------connect with GND(groud)
3# pin-------connect with J519-F3 (purple with white color wires)
For the mirror:
6# pin ------connect with the dome reading light No.6 terminal
1# pin ------connect with positive electrode (SC6)
2# pin ------connect with ground
3# pin -----connect with J519-B1
