So I have a 92 sc400 and it has a trac button but ofc it doesn’t work, i want to turn it off but obviously since it doesn’t work i can’t, is there a fuse i can pull or some way to trick the car?

 

On early SC's, TRAC is just an extra butterfly on the throttle body. You could try unplugging it and see (with the intake tube removed) if it remains Normally Open. I would feel better removing the butterfly altogether so there's no chance of it closing, but I'm not sure if that's possible without extensively modifying things. I assume a non-TRAC throttle body could be swapped in, though.
