I agree with Mr.Wright....some reason you dont have a signal from the cam sensor....could be a wire between it and the ehc shorted or loss connection or the cam sensor is bad

I'm not familiar but WSW does state your bike needs to be compatible.

someone told me that i need to make sure it was at Top Dead Center for timing ... Does this sound correct for the plug in play

You can't take this to the bank but as far as I know the EHC only provides power to your ignition module but the Cam Sensor is where you adjust timing. Top dead center does not sound correct but someone here will know what it should be set to for proper operation. I suspect if you want it perfect you need to have it on a Dyno for best results.
Your symptom in post #1 points to the cam sensor as a couple of guys have suggested. Give this test and see what you get.
