Hi I need some help. My stock RB1 Navigation Radio is going bad. So I just got a new Pioneer 6100NEX. I also have the Double Din dash kit and wiring harness with Backup camera.
I do not know where to get the Input Speed signal from and Reverse signal from. I can get the parking brake signal down at the P-Brake? I was hoping that the wire harness adapter would have the wires to hook up. But it dose not.
Can I tap in to the stock radio plug to get the wire that I need?
Any help would be great!

 

Last time I did a Navi unit, I used the VSS wire and reverse wire that are found in the 4th connector in the PCM under the hood on the pass side firewall.

Now I just use my tablet which does everything my head unit used to do and more
