The normal signal path is: speed sensor -> gauge cluster speedo, then gauge cluster -> ECU. The ECU gets its speed signal from the cluster stock.

I'm not familiar with your setup, I guess it might depend on which wire you used into the cluster since there's technically 2 "speed" wires. (One FROM speed sensor, and one TO ecu)
