re: 91 Civic - wiring fuel injectors
all of the yellow with black (or black... whichever wires are the same color between the four injector leads) are the 12v supply and should be joined together in some fashion. solder, junction connector...
the multicolor wires (different color for each injector, normally blue, red brown and yellow) go the the "A" connector on the ECU pins 1, 3, 4, 5... IIRC. The ECU grounds these sequentially to operated the injectors.
