'05 F150 Vehicle Speed Sensor

Looking at the 2004 F150 WDM
The rear axle speed sensor goes straight in to the ABS control module (located in eng comp, left side fender below air snorkle), via a twisted pair wire. One is Light Green w/ Black stripe and the other is Light Green w/ Red stripe. They hook into terminals 22 and 23 of ABS plug C135. From there it goes to the PCM and, via splices, to the insturment cluster. The output from the ABS module is another twisted pair; one wire is White w/ Light Green stripe (CAN Bus +) and the other is Pink w/ Light Green stripe(CAN Bus -).
The PCM is located on the r/h upper firewall. The wires (W/LG and P/LG) are on terminals 2 and 3 of PCM connector C175b.
Hope this helps!!

Donsfx4: Thank you. That was a very complete answer, and think it is exactly what I need. I'll take a look and drop you a note. more
Lashlaroo and Johnnyboy:
I can not figure out why it needs a speed sensor. I thought the position of the sats relative to the movement was enough to calculate the speed. You know, it's a math thing! Now, there is a plausable reason for not knowing what the heck is going on.
Actually, I believe that the monitor uses the sensor to reset its calculation automatically and more accurately read out the speed and estimate distances. Not sure though, but I think that is what Johnnyboy was stating.
Thank you folks.
