Vanguard 16hp v twin

[FTS902]

I have a 16hp Brigs and stratton vanguard V-twin. I intend to use the motor for kart.
Because it will be on a different vehicle, I need to remove some or all of the safety sensors (one for brake, one for seat, and one for mower) but I'm not the best at wiring.
I did however spend some time today to draw up a schematic of the entire system. If someone could look at it, and give me some tips as to bypassing these features I would be very gracious.
I only need the bare minimum, and I'd like to replace the ignition system with a on/off switch and push button start only. nothing else.

if your just trying to bypass the safety switches then cut the 2 wires and twist them together or you could just unplug it and stick a paperclip in the two slots and that would bypass it
