I am amazed nobdy here has a service manual and can share?

I am getting closer tonight on finding info. Seems I located the speed sensor on the diff and plugs up into the truck area. I will have to find the wire codes so I know what to look for up in the front engine bay. It's always fun being first, especially when no one is helping with info. Seems that is typical for me when I ask for help on boards. I guess my questions are too tough (sarcasm)
