.... It's got me thinking if I could somehow wire the signals from the passenger switch to, in my case, the Canadian PCB and have auto passenger window? Hmmm...
I'm seeing a couple of ways of doing it.
You could install a complete left hand "control panel" from a North American car in your passenger side with only the main "auto" switch connected to your glass. That way the "molding/bezel" should fit right in.
But, only the passenger would have access to the button and the passenger switch on your main control is a three way switch (up, down and off).
And the switch needs to be a four way switch (up, down, auto down and off).
Plus you'd have wires running back and forth between the two front doors.
Another option is to get another PCB like you have in your hand.
It looks like the three other window switches plug in to the PCB and that's good because you can disconnect the passenger switch from your drivers side PCB and plug it into (solder in wires) into the second PCB and hook them into the Auto switch.
I know the passenger switch is only three way but I'm pretty sure it can be wired for.. Up, Auto down and Off.
I had my car for two years before I realized it was a four way switch.
I would always push the down button all they way (auto) and the glass would start it's way down.
When the glass was where I wanted it I would just pull the up button and it would stop.
I'm pretty sure hitting the up buttons sends a signal to the "auto circuit" to cancel the auto down.
If you do it this way, (and my guessing is correct) all your switches will stay the same, the second PCB is tucked under your control switches and it just taps into the wires going to your passenger door.
The passengers switch works the same (push and hold up and push and hold down) and your passenger button is up and auto down (until you hit the up button).
