Are The Wiring Diagrams for Automatic and Manual GUs Different?

Recommended Posts

After swapping the Allison in my truck for a manual and reprogramming the truck, speedo blanks out (dashes) and speed dial stops working between 25-30 MPH. I was told that the wiring from speed sensor to ECM is different because the Allison has a TCM. I have been told to compare wiring diagrams and do some rewiring from speed sensor to ECM. Does anyone know this for sure, and can someone provide both wiring diagrams?
