Power Window Switch Installation Guide

Note: I will be adding more pictures, but this should be enough to get you going on your install.

Welcome! Installing your power window switches is really, really easy. If you’ve replaced your stereo, you’ve done way more than this install already. If you’ve taken your console out of any reason, you could probably skip to step 4.

Let’s dive in.

Step 1: Remove the center console

This picture shows the NA Miata Center Console with the location of the screws you'll need to remove in order to take the console out.

Put your car in neutral, pull the parking brake, and remove the shift knob.

The image above shows the location of the five screws you’ll need to remove in order to take the console out. Your OEM power window switches and ash tray light are still connected, so don’t pull too far when you yank the console out.

Step 2: Disconnect the power window switches and ash tray light

Step 3: Remove the OEM power window switches

There are either two or three screws holding your OEM switches in. My Miata didn’t have power windows. I had to install them in order to develop this product. There were only two in the blank that came with my car, but it looks like the console was designed for a third screw for OEM power windows.

Step 4: Check your new buttons

I’m not sure if this step will actually be necessary, but you should do it just in case things have shifted while in transit. Once they’re installed, they shouldn’t move around.

Check to make sure the buttons haven’t rotated while being shipped, line up the buttons and tighten the nut for each one if necessary.

Check the wires going into the relay to make sure none have come loose during shipping. This is highly unlikely, and won’t happen once they’re installed, but you should check to make sure all of the wires are still pushed all the way in.

Step 5: Install the new buttons into the console

This is where you’ll see how tight of a fit these buttons are. You will probably find that you can get the buttons to sit aaaallllmost where the need to be, but you need to push them until the snap into place before you can screw them in. The fit is so right in my Miata that I could run them without screws. You shouldn’t do that though. Once they’re in place, screw them in using the same screws you removed from the OEM switches.

Step 6: Do you even ash tray light, bro?

Some people are blissfully unaware that their Miata came with a safety feature that has long since gone the way of the dinosaur. A tiny little t10 light illuminates the ash tray/cup holder. Apparently it was a common feature to help smokers ash in the right place and not burn their cars to the ground. If you don’t have the ash tray, the little light is not very noticeable, and probably burnt out years ago.

My power window switches piggyback off of this little plug to power the illumination circuit, so I provide a free t10 LED to replace your incandescent one. If you don’t use the ash tray light, you don’t have to use the LED either. The switches will work fine without it. However, if you do use the ash tray light, you should swap out your bulb for the one I provide.

Unscrew the bulb holder. Remove old bulb. Insert new bulb. Plug the ash tray light connector back in temporarily. Before you screw it back in, turn on your interior lights to make sure it lights up. These bulbs are directional. If it doesn’t light up, take the bulb out, turn it 180 degrees, and put it back in. It should light up now.  Unplug the ash tray light connector. Screw the bulb holder back in.

Step 7: Install the new switches into the console

This one’s about as straight forward as the come.

Step 8: Route the Wires

This picture shows the wire routing for my power window switches

This is probably the step that most needs pictures to illustrate. There are a lot more wires to deal with than the stock switches. You have one un-bundled set of wires for illumination and two bundled wires that connect to the OEM power window connector.

Start with the illumination wires. Pull the wires and connector coming from the ash tray light down toward the side of the cup holder/ash tray area. Plug in the matching connector from the power window switches and run the other wires to the front of the console. Be sure to run them under the little tabs beside the shift boot.

Next, run the two bundles of wires over to the same side as the illumination wires and tuck them under the same tabs.

Step 9: Put it all back together

Plug the connectors in. Put the console back in. Enjoy!

Thanks again for purchasing my power window switches. I really appreciate it!!
