    Default does polarity matter in wiring injectors

    okay i had a boosted civic and i installed dsm injectors. that means i cut the four black and yellow power wires from the injector clips and connected them to a resistor box. after i took the turbo off, i put the original injectors back on, but i connected the black and yellow wires back to the clip in any order. my question is that does each black and yellow wire have to connect to a specific injector? thanks for ur help in advance

    No it doesnt mater because the 4 wires connect to each other anyway. all they are,are grounds anyway. the red,blue,yellow,and brown wire is where it matters.
    sounds like you may have put the wrong injectors in some how.

    the individual colored wires are your triggers...don't get those out of order. the common wires (blk/yel) are ok to tie together and wire to the resistor box. if you are going back to stock inj, you will need to remove the res box and return the wiring back to stock. i would have the polarity the same as it was stock to remove any doubt if you're having trouble.
