What year is the car? I will assume it is 2000 or newer.
The remote starter will disengage once the brake is apply unless the brake wire is not connected probably on your alarm and starter unit.
The TACH wire will monitor if the is running.
Yes, they can be found at "ignition coil (fuel injector)
distributor wire". The TACH wire has to be learned(program into the unit).

Use DEI part number 555S to bypass. *1 Keyless module is behind the glove box to the right. *2 To meter the brake wire, must turn ignition on. *3 Low beam at the headlight switch is GREEN/ red. *4 Only if equipped with factory alarm.
