To connect the Pilot to the sensor you need a PalmPilot Modem Cable (or a hot sync cable).
You also need an additional adapter cable from the modem cable to the sensor (actually the Cateye computer holder). For the additional cable you will need a Female DB-25 Connector and a printed circuit board (experimental type) (Maybe someone has a better suggestion) where you can solder two wires. The printed circuit board should fit in the holder where you normally put the CatEye Mity-2 Computer.

You will need a Male DB-9 Connector and a small printed circuit board
or something which will fit in the CatEye computer where you can solder your wires

The Cateye Mity 2 Sensor works quite simple, it's like a switch that closes every time the magnet passes the sensor so any sensor that works like a switch should work. I have tried a simple burglar alarm switch a (N.C) type which closes when the magnet passes, it works fine.
I have also connected a Sigma RCS Wireless to the Pilot. And it works using the same connections as above. But my experiences with the Wireless was not so good, it seemed that I had problems adjusting the sensor. I lost contact several times, maybe someone else has better experiences with Sigmas.
But please be careful. Don't experiment unless you know what you are doing...
