2009 Mazda 3 Cruise Control

[nicneufeld]

So I'm looking at adding cruise control to my inlaws' Mazda 3. Its an 09, and I found a Rostra aftermarket piece, but I've also found sources for the original mazda parts, which I gather are sort of plug-and-play since the cruise control functionality is already built in.

Does anyone know the 2009-specific part numbers for the cruise control brake switch and the steering wheel switch cluster for cruise control?

Many thanks!
