Step 4Step 3: Polarity check
Get your jack female connector and remove the plastic part from it , and then plug it into the jack coming from your ball.Now get your power supply's wires and be sure to insert the wires in the plastic part of the jack female connector , i will explain why just a little bit later.
Now use your power supply's wires to check all the 3 connections on the female jack and find the correct ones which will light up the LED . Solder the wires in the correct places on the connector and then use the plastic part to twist it around the connector , so now it's isolated(if you solder without the wires coming out of the plastic isolation , you will have to cut it to put it back).
Now put batteries in your battery holder and it's all done ! The next time you want it to light up just connect the two jacks together.
Now you may notice that i used a 9V battery clip from an old AC/DC adapter for my supply , because my battery holder was using a 9V clip .
