You will need to use obd-1 or 2 injectors. Then you take the 4 yellow wires that would go to the resistor box and wire them together. Then splice the wires wires into the red wires that go to the resistor box. Did it on my b16 setup so I know it works. The red wires are 12v's but obd0 injectors are like 6-8v's so thats why you need the resistor box. However obd1/2 injectors are 12v. I also have a risistor box for sale if you want one. $10
