I am new to the toy adapting world. My son is 5 and has motor and vision impairment. I am attempting to adapt a few of his toys but I am stumped by the Beatbo Jr. The three wires (brown, brown, and red) and not sure how to connect them tot he red, white, and yellow wires of the headphone jack. In addition to this, the wires from the circuit board are connected with the white connector leading up to the body and head of the toy. So I am not entirely sure which wires to cut and connect or if I must solder directly onto the circuit board. Any help would be appreciated.
