Hi all,
We are running a brake over travel switch in our fsae car, when the switch is hit it kills ignition and fuel. We are doing this by using a digital input and using the 31- stop switch option in the ecu that cuts fuel and ignition.
Our brake over travel switch activates a relay and this sends a single 12v to the signal of the dig in on the ecu.
My question is where do we connect our 0v of the dig in?can it go straight to ground?
Thanks
