Default Need help with Raptor Shift Light

Well I hooked up the light to the PCM using a ground screw, pin #10 (white Tach lead) and #39 (red 12 volt reference) in my 2002 WS6. The light has power, it tests at startup and confirms the setting by blinking 5-7-8 in succession (5,000 rpms, 700 rpms, 8 cylinders). The only thing is that it will not light up at the desired rpms. I take it to and past 5700 rpms and it doesn't light. I checked the connections in the tach out wire tap and it seems good. I have tried running 6 cylinder mode at 5700 and it still does nothing. Anyone know what's going on?

Yeah, it always seems weird setting a V8 for 4 cylinders but it works. Now go test it out on some open back road.

I set it to 4 cylinders and it worked, I tested it on the way to and from work today. It is 1-off 2-on 3-off, and according to Raptor that is for all GM ls1/ls6. Which is weird because if you look on the sheet where they tell you the pins it says to set it to 6 cylinders, but on the Adobe Reader instructions it says 4, and 4 is what works. I don't know, but all I care about is that it works and it does so I'm happy. Thanks for your help guys.
