You can use low impedance injectors in your harness.

You will need to put a 10ohm 10watt resistor in one fo the inecjtor wires (PER INJECTOR)

This drops the resistance down to acceptable ranges for the injectors.

This is what I have done on my car.
I have high impedance priamries and low impedance secondaries(planning on higher secondaries and high cc injectors are generally low imp)

You can get them from radioshack.

Make sure they are 10ohm by 10 watt.

I think they were like 1-2 bux each.

Here is a pic of my setup.
The box with the duct tape on it is also from Radioshack.

I used it to isolate the resistors incase they create any heat and also to keep from being fucked up.
