Does anybody know what the output of the wheel sensors looks like (i.e. electrical characteristics)? I need either:
  1. Install a transducer and some magnets on a rear wheel
  2. Use the existing wheel speed sensor signal
Obviously, using the existing speed sensor signal would be ideal, even if it requires a little electronic massaging.

Searching through the forums and through some simple experimentation, I know that it some sort of magnetic based sensor. I just don't know what it outputs in relation to the actual wheel speed.

If no one knows, I'll be hooking up an oscilliscope on Tuesday to find out... :cool:

[edit to continue this...]

After much searching around on Google, I found this article. Obviously, the "new" style would be preferrable, as it looks easier to play with.
