Jason - I tapped into the trim switch using soderless blade-type connectors. Basically, I made a Y shaped connector with a female end on two legs of the Y and a male end on the other. I unplugged the lower power wire of the trim switch and hooked it into the Y, then I plugged in the trim switch on one female end and the FF into the other. Power was spliced between the two. For a ground, I just bolted the FF ground to a hole drilled into one of the metal plates under the switch plate. I used a multimeter to find a good solid ground. Works like a charm and doesn't negatively affect the trim switch, which, afterall, is used sparingly anyway.
