Hi Guys,

I've just installed a new Pioneer head unit with GPS Navigation and I'm supposed to connect my vehicles speed signal wire into the head unit. This allows the NAV to know where it's going once in a tunnel and the GPS aerial doesn't work anymore.

So I've searched the web and been told it's a purple/white wire but the answers for it location are inconsistent. So far it's either on the drivers side firewall in a group of connectors or it's located in the left hand corner of the dash...maybe for when the factory SAT NAV units were installed. So does anyone know exactly where it is before I start pulling my car apart again?

BTW, my car is a 2004 VY SS. Thanks guys
