I want to install a Pioneer Avic-F90BT in my 2004 GS300 and have a question about the wiring. I need to install a wire on the cars speed signal input but I am not really sure as to where I can connect this wire. Have any of you performed an install and can you help me? Thank you.

 

I looked up 2004 GS3 and it's near the left hand driver side. Here' a pic



If you need the diagram of the vehicle speed sensor let me know.

 

Here's my crude copy paste since alldata doesn't let me export jpg's or
anything.
Hope this helps.
