Have an 0411 ECU and a Viper 3 wire vss (power, ground & signal). GM VSS is only a 2 wire (High and low, sine wave). How ,if possible can this be wired so the ECU gets the proper signal? Thinking the ground on the VSS goes to the ECU VSS 'low' and the signal on the VSS goes to the ECU VSS 'high'?

Currently the VSS is wired and working normally under a 5v power via step down transformer. The signal is run through a digital to mechnaical speedo converter (Cable X). This is happy. I have swapped in an 0411 ECU engine management system and want the ECU to know the vehicle speed.
