Ok so I installed my new 450 fuel injectors in my 97 civic and i did not install the resistor box yet. the car did not start and im assuming its because the resistor box is not installed. The resistor box comes with a different head unit and wont fit my civic connection. Im deciding how to hard wire it because on the stock wires there are 8 black/red wires and on the resistor box wires there are only 4. How do i hard wire this right?

 

97 civ is obd2 i dont think you need a resistor box...?
