speed sensor wire
 

I'm looking to hook up a alpine navigation unit and I can't seem to locate the speed sensor unit wire.I know the wire is at the pcm but what colour is the speed sensor wire coming of the pcm is it? Looks like theirs to PCM's J1 and J2 and from what I understand its in the J2 compartment would anybody happen to know what pin number the speed sensor is attached too? Any help is appreaciated
I forgot I have a 2001 STS Seville
