Pretty sure you need "Running" indication which would be the DRP.
DRP is a square wave.
Here is a variable one I built for my test bench but you could just make it constant RPM.

The speed sensor input was most of the conversation was about because it needed a sine wave for magnetic sensor,
Square wave for the optical type but you don't need that.

I haven't had time to work on the car lately. I do believe the DRP for me is a 0-5v square wave. I hope I can just split it. I just wanted you guys to know I appreciate the continued support. I haven't gone anywhere, just haven't been in the shop.
