Response from Jonathan: Hooking up the trackball for Golden Tee 99 should be a pretty straightforward task. In fact, the manual for Golden Tee 99 (which you can download here: http://www.crazykong.com/manuals/GoldenTee99.man.pdf) is very detailed when it comes to working with the trackball. It has the pinouts as well as instructions on how to prep the trackball for installation. We recommend looking over it to see if it helps you understand how to accomplish this task. Of course, feel free to contact us again if you have any specific questions about the installation process. Hope that helps.
