Lastly, if you're using low impedence injectors on a high impedence NA harness (87.5-88), you will need to buy resistors to wire in (www.mouserelectronics.com, I bought some 6 Ohm, 10W ones here) & you will need to modify the injector clips or buy low imp. clips and splice them in. High impedence injectors have a tab that is centered, while low impedence have an offset tab (mine did at least, chime in if some don't have this). I solved this problem by carving some of plastic out of the clips with an exacto knife.


what do i have to do if i have a (high) impedance injectors with a NA (low) em harness???
do i cut the pig tail from the fuel injector resistor relay and connect all the wires together????

Unplug the resistor pack from the harness and jump all 5 pins on the harness-side together with some short pieces of wire. Hailers has a picture of this in some of the threads that come up on searches.
