HI Everyone!!

I need help locating the speed signal lead wire for a Evo 9 MR. I just brought the JVC KD-NX5000 single din navigation system,and for the navigation to work you need to spice into this wire. Heard it is a Black/Yellow wire marked PCM behind glove box, but I can not find it?? or if this is true? Thank you for any help.

 

Here's the info from my database, hope it helps.
Speed sense: white/black or black/red at data link connector. The data link connector is under the driver side dash.

 

Thank you for your help!!!

 

where are the wires that i attached the reverse and ebrake wires to; as in where are they located and what do these wires look like?

thanks
