I'm 1000% sure.


I've since started working on a Toyota for ChumpCar / LeMons racing. It works very similarly, except with vacuum switches. The clutch pedal and brake pedal both have a vacuum switch. These are connected together with a T fitting, which then goes into the firewall to connect to the engine vacuum.


Knowing what I know about Toyota and their tendency to not change things, they are probably using the same electrical circuit on our cars to detect either brake or clutch, much like the above vacuum circuit.


I'm probably just going to turn it off also. Thanks for looking though.
