Default EP3 Harness & FA5(PNN3) Trans. How to make speed sensor work??

I have a 1995 Civic K swap. 2003 SI Harness with a PNN3 Trans. All hooked up to a KproV4 Bluetooth ecu. Trying to figure out how to make a speed sensor function on this vehicle.

Thanks in advance for any help provided.

If the KPro was installed by Hondata, you may be able to use the electronic conversion function in the KPro software. Use the "Help" file to show you how to wire it up correctly for this. Otherwise, the only way is to convert the wiring on the engine harness for the VSS from low frequency signal type (VSS plug at the back of the trans and spins off the differential) to a high frequency signal type (VSS plug located at the front of the trans and gets signal off the mainshaft), purchase a VSS converter (like one from K-Tuned) and wire it into the engine harness to convert the VSS signal to a value that the ECU and dash will understand.
