After adding a positraction (Trac-lok), the speedometer doesn't work. I found out that the spedometer signal comes from the rear differential and the trac-lok is missing the toothed ring gear carrier. Did I buy the wrong trac-lok? Is there any other options to get the speedometer and ABS to work?

The speedometer signal is generated by the vehicle speeds sensor in the rear of the transmission. Here is the location so you can see if it is connected. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
