Thanks a lot for your help. My original switch is exactly the same as your pictures (auto mode at the driver side). The US version switch that I got has the same socket (I could plug in but it won’t operate) with auto mode for both front windows (the switch is from 2017 WRX). I could find wiring diagram for US switch but not for my current RHD 2013 XV(from Thailand).
The reason I need to use this LHD switch is that I bought Subaru Levorg window switch panels to use with my XV which require new set of passenger window switches. So I bought full set second hand switches (WRX2017) from ebay at 50usd that includes: 1 master window switch (pluggable but won’t work), 1 auto switch (different socket), 2 normal switches (work, with a bit of modification)
The original driver side switch fits Levorg window switch panel but all other switches have shiny silver button tips. That’s why I want main switch to match with others.
I couldn’t find secondhand RHD driver side switch anywhere on the internet(that ship to my country) and have no idea which part number I should get.
