Just purchased my first golf cart, a 2006 EZGO PDS and am having a blast with it, and with learning about how it works, and what mods can be done. My first project was to install the speed chip/plug. It is used primarily for golf. After reading the wealth of info on Cartaholics Golf Cart Forum I decided to install a switch to toggle between the speed setting and the mild terrain setting. I cut the small loop and soldered wire leads to it and installed a switch. Now it can has a mode for me and a mode for the kids. (The switch is under the seat, so switching it and the Run/Tow switch can be in proper sequence) Thanks for all of the great info. I have other mods planned such as a state of charge meter and some bolt on accessories.
