Due to good reviews I have just purchased and installed Acewell 2803 on my '03 SV. The reason I purchased is because I converted from N to S and didn't like how stock speedo looked or mounted. I needed something small to fit behind windscreen.
I know this thread is old, but I thought I would share some things.

Alternate mounting location: simple bracket off of ignition switch mounting bolt (between ignition switch housing and upper triple tree).

Setting up tach:
a. Splice yellow tach wire directly primary wiring of coil. I used coil on left side of bike and connected to the white w/ blue wire.
b. Connect black ground directly to battery. I first wired to instrument cluster ground, but had a lot of noise (jumping) in tach reading. Then, I ran a wire directly from battery to existing connection (2 ground 'inputs', or 3 way connection), but noise did not improve. And finally, speedo ground directly to battery, and the tach ran perfect.
c. Tach set to 1.0
d. I did all my wire connections in parallel with stock speedo connector. This way I was able to keep the functionality of stock speedo and test all idiot lights and tach reading, to make sure they were correct.

Speed sensor location:
a. The manual states that it should be parallel to vibration source. Unlike other people, I interpreted this to be parallel to shock movement (perpendicular to ground). I can't see this being too critical because every point will be fixed (relative to each other).
b. The magnet should pass across the sensor at a single point, unlike sgf323's original picture. I believe this was the issue, and not that the sensor was not parallel to ground. So, with these two points, my thinking is you have 4 options:
Perfect location: but makes for a long bracket that was too flexible
Bad:
Bad:
Okay: No 'anti-vibration effect'
5. Current bike condition... almost done. Just finishing up license plate bracket and windscreen mounting.
