You will need to install it onto the throttle body, but leave the 2 mounting screws slightly loose to allow it to slide back and forth. Position the sensor so that it reads 0.98v at closed throttle, then tighten down the screws.
Setting it straight on won't do it. You have to angle it a little so when you put it on, you will have to twist the TPS a little to get the holes lined up. You basically are pre loading the sensor a little. And it doesn't have to be .9v range. .7v-.1v in that range will be fine. You could even go a little lower or higher.
