Unfortunately I don't have any fitting advice as mine was already on my golf when I bought it.
But I will say I love this mod, when people jump in my golf and I say press that button there for me (all casual), then they do and they're all like "woooow".
Mine's a crome button with a crome surround, and whoever fitted it must've done it properly because the button won't work whilst the engine is running, and you can't start the engine via the ignition.
I love it.... Thumbs up for me
