Can anyone help with the speed limiter?

[Wyatt]

So I got my new Radkick 7-Speed a couple months ago and it goes 20 which is okay but I can definetly feel it can go faster. I know that on some RRs you could remove the speed limiter so the bike would go faster. I figured out how to reach the controller and there are a bunch of black wires with one red one but I don't know which is the speed limiter. Could someone help me figure out which one to cut?
