My windows switch modification for automatic roll-up windows became a very popular mod among Miata enthusiasts. However, the original modification, for most people, was somewhat difficult due to high precision soldering. To make it more accessible, I designed an external controller with a wire harness, which is now an easy plug-n-play setup.
The new controller has a little switch for selecting windows behavior during opening the top. Some people would prefer the windows to automatically go down, while others prefer the windows to go all the way up.
he new plug-n-play windows controller for Soft Top is available in my store.
Now it works with MX-5 RF as well. RF version is software only update.
