i got some blue top dsm 450cc injectors. how do i hook them up to a 97 y7 civic with obd0 clip? do you need the little black plastic part at the bottom of the injectors. is there a ring i have to buy for it.

you need obd1 civic injector clips or dsm ones to put them in, just split the wires and hook up the new ones. I thinking your talking about the little plastic by the tip of the injector, if so No you dont need it.
