@daneelliottd532 we need to know your exact model. There are some different variants of the PS2. [https://www.amazon.com/Vivi-Playstation-Controller-Repair-beginning/dp/B012X8MCIY|Here is] an example of what the cable for models beginning with SCPH-3 & SCPH-5 look like and it shows you how specific you need to be so we can try and help you.
As for the ODD, it will again depend on the exact model Sometimes it's just easier to replace the complete drive where other models just do not allow that
