There is one vss. It could cause the problem with the speedo, but I question it has anything to do with the ABS.
What I recommend is taking the truck to a nationally recognized parts store and have them scan the computer for codes. If the light is on, there will be a trouble code stored in the computer. Then, you'll know where the problem is coming from. NOTE: Most of these parts stores will scan the computer for free, so there is no money out of pocket to identify the problem.
Let me know what you find
