    You only need the resistor box for OBD0 injectors.

    I was referring to Civic and Integras but yeah, the F/H family is more complicated. My OBD1 Accord has a resistor box too.

    so if i have a p28 and run the wires from the ecu to obd2 injectors and then ground out the other side of them i should be good right?

    No, you do not ground out the other side. The ECU controls the injectors by grounding them out; the other wires(usually yellow with black stripe), goes to a 12v switched power source.

    But, yes, you just wire the (Civic or Integra) OBD2 injectors directly with no resistor box.
