Electrical problem
1999 Dodge Ram V8 Two Wheel Drive Automatic

For the last couple of days when I use the cruise control on my truck every few seconds it would rev up like it does if you're going up hill but I would be traveling flat while it was happening and my brake light would come on, then yesterday as I was going down the road my brake light and abs light both come on and my speedometer completely stopped working. I was told it was the cable but the Dodge dealership says my truck doesn't have a cable on it. That it's one of two sensors. Is there a way to test the sensors to see which one it could be. And if so how?

They are correct. There is no cable. The speedo is run by a vehicle speed sensor. Based on your description, the output speeds sensor is bad.
