Which cable for VSS? (speed sensor)

[garylees]

I need to find the speed signal for a HUD(head-up display) in my 09 Mazda5. does anyone know which cable for VSS? thx!

 

[garylees]

The stock radio had speed sensitive volume control so if I could locate that wire could I tap in to it for the VSS signal?

The speed sensitive volume wire at the audio connector is from data on the CAN network, and only the factory unit knows how to decode this data. The VSS signal pin you need is available at the instrument cluster connector.

Here is the thread that discussed it.
