You can't miss it once you get squeezed under the dash. You might look for chafed wiring although I would expect a bare wire would cause a blown fuse. 2.2 A is a pretty hefty current, imo. The BOO is used for a lot of things and the Haynes manual (less than twenty bucks at AutoZone and even cheaper at Borders but it is not usually in stock) has electrical schematics in the back showing all BOO connections. You are correct that it is used to toggle the torque converter off (if that is how the tune is set up). I will check out my Haynes and post up more info (a little later). Stay tuned.
