Here's a guess. The speed signal, I would think, comes from the speed sensor. The speed sensor is located on the differential. As the name suggests, it tells you what the speed is. Are you having problems with the speedometer at all?

I'm sure there is a way to check it. However, I don't know how. Maybe someone else on this forum has an idea.
