Can someone help me figure out the correct wiring for the injector resistor wiring for my evo 9? My tuner cut it and soldered all the wires together so I could run high impedance injectors. I am going back to stock injectors so I need to solder the harness back onto the module.
Off the top of my head I THINK as long as you get the white wire to the white wire the blacks shouldn't matter. Basically the white wire supplies power to the 4 resistors, one resistor for each injector. It doesn't matter which resistor goes to which injector. You can test resistance between the white wire and each of the black wires and they should be all the same, but if you check resistance between two blacks it should be double what it is between a black and a white. If I'm wrong about that part then ignore my advice.
