Need VSS wire!

I just installed a new alpine nav system is my 04 civic yesterday. But I still need to find the VSS wire for the system. Does anyone know where i can find this under the dash??? It will suck having to pay an alpine installer to do this for me...

On the fuse/relay panel start at the upper right corner. The second row down of green plugs, all the way on the right side of the box. The wire is blue/white. (that is a blue wire with white striping) You also might see a solid blue and white/blue (white wire with blue striping) right next to the blue/white, so be careful which one you tap.

K I will give it a try
Thank you!!!!
