Atp And No Gauges

Test Drive
I have a 2004 nissan xterra V6 non supercharged. My gauges just went with no warning and the ATP light came on. I have replaced the instrument cluster, I have checked all fuses and relays, according to wiring diagram I have narrowed it down to the ECM and speed sensor harness. I tested the vehicle speed sensor and it checks out. Anyone have any ideas?
