2002 Explorer VSS speed sense for Navigation

[Scott2008]

Hello- I'm installing an Eclipse AVN30D unit into my 2002 Explorer 4-door Eddie Baur 4.6L. I have researched and keep seeing a gray/black wire to search for. I am having a tough time.
1) The PCM- which passes through the firewall on the passenger side- I have opened up each wire loom under the engine comp goes goes directly into the PCM- there is no gray/black wire- I can tap under the hood there, could it be another color? (or is this not the PCM- LOL)
2) I checked the black box located behind the glove box above the pass kick- don't see a gray/black there.
3) Checked the 4x4 module- no gray/back.

I'm kinda lost- can anyone tell me a location, wire color where I could tap for a VSS wire (Speed Sense Wire) for a navigation unit?

Thanks Much!

Anyone out there?

Try posting in the audio section. Or at least the modified section. Might get better luck.

did you look in the wiring loom that comes out of the rearend?
i am pretty sure that is where the vss gets it's signal from,
if it does, follow it up the side frame ,

At the ABS control module, there is a light green/black wire and a red/pink wire. Those are the wires from the rear speed sensor.
