Tools/consumables:
Coat hanger
Tape
zip ties
butt connectors
Crimpers
wire cutters(dykes)
wire
Drill+bits
Parts:
JDM mirrors
Switch(JDM mirror switch)
JDM mirror relay
The first step is to remove the door panels and remove the mirror switch assembly from the driver's side door panel.
Remove the 2 screws towards the top to gain access to the switch.

It will just pop out after that. Then just pop in the JDM switch.
The hardest part of this project is running a wire connecting the mirrors together. You could also use this technique if you want to run wires into you doors if you have an amplifier for your door speakers. But you can get around running the wire in the door by running the speaker wire from the amp and connecting into the speaker wires behind the radio and use the factory wiring to get into the doors.
The connector you have to run the wire through is located in the door-jam on the lower part of the door. If you remove the speaker (as seen in the pic below) it makes it easier to work with the connector. It is a PITA to separate it. You have to push down on the tab while you are separataing the connector. It's hard to do in the small door jam.
This is the side that will come out of the door when disconnected.
Now you need 2 wires inside the door so I used speaker wire since it would be easier to work with instead of running 2 separate wires you can run the 2 at the same time.
You want to drill the hole in the empty section of the connector. Then to the same on the plug side. Be very careful not to damage any of the factory wires.
This is the door-jam side of the connector.
When you run the wire out of the male connector in the door into the female side make sure your wire is on the side of the door hinge as pictured. The wire has to run down behind the hinge so the door can open and close.
Then it will go through this rubber grommet and then into the cabin.
