The CT302S9 controllers have not been made for many years now however there were a couple of different connector plans for them so even if a CT302S9 controller were available it might not have the same connectors that your original CT302S9 controller has. I checked and our controller item # SPD-24250 has all of the same functions as the CT-302S9 controller.

We have all of the same connectors available that the CT302S9 controller has which could be installed on the SPD-24250 controller, however I recommend changing the connectors on the scooter instead so the SPD-24250 will plug into the scooter without modifying its connectors. This way the next time a controller needs to be replaced a SPD-24250 can be used for a plug-and-play replacement.

Here is a link to wiring for the CT302S9 controller: http://electricscooterparts.com/hookup/SPD-CT302S9.htm

And here is the wiring link for the SPD-24250 controller: http://electricscooterparts.com/hookup/SPD-24250V2.htm

Matching connectors for both of these controllers are available here: http://electricscooterparts.com/wireconnectors.html
