I made a new harness for my drift sr20det red top car and i have a question, pin34 start signal from ignition switch. I need to know, this start signal is only when you start the car? I m not sure.
Thanks!

Yes, it tells the ECU that the starter is engaged so it goes into cranking mode. The engine will be very difficult to start without it.
