Lap bar switch fault

[Ctrain117]

Needing some help here. 2018 ASV RT120F I keep getting a lap switch fault, it started last week and I raised the cab and cleaned connections into the main controller and it went away for a few days. Now after I worked on my A/C condenser inside the cab it's back and won't move at all. I've tried cleaning the connections again and checked for damaged wiring with no luck. Can anyone point me to which wires specifically I should be tracking for that switch? By the way the switch has been bypassed for years with no issues until now, it is still currently bypassed
