I am curious why no one is asking for the clockspring that would go in any non-SRS toyota. Its more costly then these buttons... Plus its not just for any corolla. Its specific to Altis. Whose clockspring may or maynot support additional wires for controls.
@Poster. I dont intend to spoil your thread. Its great stuff especially when many people are looking for it. But you need to provide complete details like @zunny bhai or @fireblade do.
