KidTrax Audi R8 GT help

Hello Everyone,

I am looking to modify a KidTrax Audi R8 GT with 6v battery for one of my patients with a switch; basically disconnecting foot pedal and making it switch controlled. However, the wiring is much more complicated than the McQueen car and TMNT truck that I modified during Sam Logan’s course…Has anyone completed this modification or one similar to this? Also, does anyone have electrical engineering expertise that could provide input? Thanks so much!
