ok, when you look at your stock injector wiring, each injector has a black wire going to it. these are the power wires, they provide 12v to the injectors.
cut each of these black wires and splice the following together, 1 and 4, 2 and 6, 3 and 5.
now after you have splice the correct pair of black wires together, they are now supposed to go an individual pin to the resistor.
after you have routed each pair of black wires to the resistor, you will now have to route the power wire to the resistor. remember when you cut the black wires from the injectors? splice ONE of them to PIN 2 of the resistor.
o ok i think i understand.. so all the injector sides of the black wire goto the 3 wires of the resistor box.......... and the power side of the black wire, any one of them, goes to the power side of the resistor box. Man a hidden switch to that would make a great security device
