Sorry, no scanner, but I can tell ya what you need to know.
0. Find the brown/pink "hot" pump wire and cut it.
1. The red fused wire you want to tap into the "hot" pump wire on the "battery" side, i.e. the side the power is coming from.
2. The red wire with no fuse you tap into the "hot" pump wire on the "pump" side.
So, after 1 and 2 essentially the power is flowing from the power source, through the BAP, and to the pump. The wire you want to splice into is a brown/pink wire in your trunk. You can find it easily where it goes through a grommet with a few other wires and heads off under the car. On my car, I traced it back to a small computery box behind the rear driver's side wheel well, and tapped in just after the wire left this box.
3. The 2 black wires are ground (some units have 2 ground wires).
4. The two sets of red/black wires soldered together, 1 is for the pressure activated switch, the other set is for the dial controller. The way yours is soldered up, it's set up to be always on and always at max setting (which is how mine is set up a la Ed's and other's recomendations). Sorry I can't tell which set is which by looking at the pict., but I wouldn't worry about it, since it's set up how I'd think you want it anyways. Just tape us those connections so they don't short out on something.
