If you use pin 10 on the ecm then you have to set the window switch to a 4 cylinder not sure if the same is true of the other way or not?

You running the two stage Trick Engineering Window Switch (Dynotune/Nitrous Outlet)?

From the PCM I believe it you set it for four cylinder mode. You can check whether its right or wrong by holding the first button down, it will show you what its reading
