fuel injector polarity???

does it matter???

long story short, i broke the pigtal to one of my injectors, got a new one and wired it in. im pretty sure i wired the wires back to the same side of the new pigtail but i think im missing in that cylinder now, might of crossed them. im not sure.. both the wires on the pigtail are the same color. (white) and the original harness both black. assumed it wouldnt matter then but we all make mistakes haha

Re: fuel injector polarity???

it doesnt matter its just a coil. But if your looking at the plug like this the red is fused power and the black is the grounded injector trigger.
