VSS speed input wire location

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

Remove your speedo cluster and find the purple wire with white trace.

Man that is one advanced head unit :goodjob:

Thanks bud, I was going to leave this as the last resort as I'd prefer to tap into this wire at another junction point or connector.

Is there somewhere else that I can look initially?

It sure is, it's Pioneer's high-end double din unit (AVIC-F70DAB). It basically does everything (CarPlay, digital radio, plays FLAC files, has HDMI etc etc etc) except play bluray

That would be the closest spot to you HU. If you carefully peel back the inso on the cluster loom cut & solder, good to use some heat shrink too.
I had to do the same when I fitted the twin GTO guages to my VZ.

Thanks mate, maybe I'll have to give this a crack

I found an easier way [emoji4]. I asked a guy from a car audio shop. He told me that the vss wire is located on the passenger side behind the glove box... it is in a plug on the left hand side and it is purple with a white trace

This is the ISO connector with the VSS wire.

Pull out the glovebox and you'll see it on the left hand side attached to a clip

That's for the accessories the cops use.... Makes sense VSS is in there

& probably for sat/nav on higher models too.
