it sounds to me that you simply pulled out the Stylus assembly from the cartridge. You need to unscrew the screws on the top of the tonearm headshell. The cartridge will drop down exposing the 4 connector wires and connection posts. You remove those, and attach them to your OM10.
Sorry if I'm not following. I'm not familiar with the tracker cartridge, but had an MMF5 and an OM10.
