I am working on videos right now and will be posting mid to latter next week, but I will attach my Lexus IS 500 power folding mirror retrofit thread from my project there. The actuator parts I have listed there will work, you just have to switch out the base piece that adapts the mirror to body. The bottom of the actuator housing that holds the motor for the IS 500 actuator will screw together on the base plate of the RCF. You can then use a 2010-2015 Lexus RX 350 4 window door switch off eBay and swap the internal parts (Mother Board) from that into you oem RCF Master door switch and the auto manual button up top and you're good to go. Videos coming in about a week, waiting for the left IS 500 actuator to get here so i can finish up. The right is currently installed and working just fine. I'm working on sourcing the BCM for a non-USA RCF so that the auto portion will fold and unfold your mirrors when you lock and unlock the car.

For now, here is the other thread for part numbers, just disregard the BCM listed there because its for the IS 500 only. You could actually use the IS 500 4 window master switch I have posted there but its an expensive option.
