I did get an RPM sense to work. I tried to build the one referenced but while it worked with a signal generator it didn't work on the car. I bought a shift light circuit from racer parts wholesale for about $50 and then tied it to the ground side of the relay coil and had the WOT switch provide the positive voltage for the coil.
