Demonstration of the working paddle shifters I installed in my 2006 Toyota Aurion SX6 Sportivo (GSV40).
Accomplished by using a factory steering wheel from a 2008 Toyota Blade Master G (GRE156) which have paddle shifters from factory (although I swapped the plastic paddles for magnesium ones from a Lexus IS-F). Added two extra wires to the factory clock-spring and connected them to the shifter + & - wiring.
