Where does this mount? 2003 Supra SSV

I feel dumb for asking, but my throttle was acting up last weekend and I discovered the throttle housing/perfect pass control came loose from the mounting position. We had to manually adjust the knob to get the throttle cable back in line with the actual movement of the throttle by the driver. Does anyone have a picture of where this should be mounted? Boat is a 2003 Supra SSV with Indmar with Perfect Pass (I think it was called Wakeboard Pro). Any help is greatly appreciated.
