Thanks @
Tech this is perfect.
I currently have the blue TRD "blocking" sound changer installed but will now look to put the "noisy" one in and one of these plugs so I can easily turn on and off.
In a RHD car installing the TRD sound changers are a mission with lots of stuff in the way so this is a million times easier.
The simplest DIYs are the best for me!
