Disclaimer: I am not an electrician! Which is why I'm having trouble figuring out just how to go about installing a fuel injector kill switch on a 7th gen Civic. First, the schematic:
Unlike the 5th and 6th gen cars, it seems my 2005 has two FI relays (each marked "main," confusingly)--Relay 2 grounds through the fuel pump, and Relay 1 through the ECM? So, do I have to cut both of them or just one? Would cutting the ground from Relay 2 cause fuel pump issues when trying to start the car again? Would cutting the ground on just one relay even shut down all the injectors in the first place?
